Kim Jin woo is a university student who doesn’t care if he doesn’t date. In the midst of couples, he prefers to be alone, given that his standards are too high. He feels himself perfect as he’s good looking, smart, great in basketball and belonged to the broadcasting club when he was in high school. Given his qualifications, he just can’t date anybody so one day as he’s heading home, he overhears his classmates talking about his friend Jung ki sub moving into his home, Kim Jin woo can’t believe it and starts hurrying to his house.
Meanwhile, Ki sub has moved in with the help of his friend Balg um but when his friend learns that he didn’t get permission from Jin woo to move into his place, he panics and starts urging Ki sub to leave. But they are too late. Jin woo catches them and looks pretty angry at Ki sub demanding him to leave immediately. However, he nearly melts when Jin woo begs him to stay for a while while playfully poking him. Jin woo gets momentarily lost in his handsome face but pulls himself out of it and still pushes him out.
But in the next scene, we see Ki sub has moved in anyway leaving Jin woo in a pickle. Ki Sub begs Jin woo to let him stay for at least a month before he travels to the Us. Jin woo is surprised to hear that but still remains adamant, scolding Ki sub for crossing the line and invading his personal space. He ignores Ki Sub’s chicken and lies that he’s going on a date and wants him gone in six hours.
As Jin woo leaves, he reminisces about how handsome Ki sub is but with a big flaw which is that he never says no to anyone and because of that, is a player dating up to ten girls at a time. It’s time for Jin woo’s online class so he heads to a cafe to study. However, he’s unable to concentrate thinking about Ki Sub in his house but a few moments later, he sees Ki Sub’s friend Choi Balg um, a professional part timer working in the cafe. Shortly after, Ki Sub enters the cafe to meet with his friend. Seeing them, Jin woo panics and leaves the cafe without being noticed, surprising Balg um who told Ki sub he had seen Jin woo but Ki sub thinks he’s wrong because Jin woo is on a date.
The two leave the cafe and Ki sub says he wants to buy something, surprising Balg um who knows he never buys anything for himself. Ki Sub wonders how he would manage to stay with Jin woo and tells Balg um he knows Jin woo likes him. Meanwhile, Jin woo keeps seeing him and Balg um everywhere he goes. He hides to avoid running into him but eventually, he’s unable to stop fate as the two end up meeting at the point where a young man is confessing his love to a girl and she accepts. Although, Ki sub doesn’t see him, Jin woo imagines them staring at eachother as they walk closer to themselves. But the imagination vanishes when Ki sub notices him. Jin woo begins to run away but Ki sub pursues him to give him the gift he had gotten for him. Meanwhile, Balg um, confused about their dynamic thinks he saw someone he knows, Ji in ho in the crowd but he chalks it up to his imagination.
Ki sub chases Jin woo to his house, trying to get past Jin woo who has barricaded the entrance, refusing to let him inside but he ends up pushing his way in pleading with Jin woo that he would be like a cockroach in his house and not disturb him. Jin woo insists he leave but Ki sub is relentless and enters the house, telling Jin woo he knows that he likes him. Jin woo is shocked and follows him inside asking how he knew that. Ki sub replies that his feelings is written all over his face. Jin woo is surprised he knows his feelings and still came to his house. He calls him trash but Ki Sub doesn’t flinch and asks him why he didn’t confess to him like others. He thinks it’s normal to confess when you like someone. Jin woo is in disbelief at his words but Ki sub is serious and really wants to know the reason why. Jin woo isn’t having it and tells him to leave.
However, he freezes when he sees the shoes Ki sub brought. It’s in blue and red color and Jin woo gets angry when Ki sub tells him it was buy one, get one free. The other is for Balg um. It makes Jin woo remember how familiar Ki sub is with love, getting things he wants so easily. Annoyed, he tells Ki sub he isn’t going to confess to him because he is the worst. Ki sub then tells him that at first, he only wanted to sleep in his house for one night but now, he will make him confess in one week at exactly 10:15 pm but Jin woo stubbornly insists he can’t confess to someone like him but in his heart, he knows he likes him.
The second episode is in Ki Sub’s pov. He acknowledges he is the type who always agrees with everyone. He even once agreed with an obvious female scammer to the extent the woman got frustrated with him. He believes it’s natural for people to express their feelings. After all, we only live once so when he gets confessed to by anyone, he easily accepts. He doesn’t understand why some people refuse things given he had never refused anything in his life. But he became curious when he saw Jin woo for the first time at a student dinner refusing to hold a woman’s hand and choosing to drink a big bowl of alcohol instead. This intrigued him and he decided to drink the alcohol for him resulting in him being drunk. Ever since then, Ki sub has been curious about the kind of person Jin woo is, being able to refuse things. He also knew Jin woo liked him because he looked at him the way one would only look at the person they liked. He was often confessed to so he knows.
Now, he was telling Jin woo to like him but he responds that he must be feeling proud since people often confessed to him but he would not do that because he wasn’t his type and that he’s eliminated from his list. He would rather remain single than date someone like him. Ki sub is confused and just then, the lights go off signaling to Jin woo that it’s time for bed so he lets Ki sub sleep over but warns him to leave at 7:am sharp
That night, Ki sub is suffering from a cold because his window is unable to close. He shouts to Jin woo who is restless in his room to get him some blanket or let him sleep with him but thinking he’s only finding an excuse to harass him, Jin woo shouts that he shouldn’t dare or he would kick him out. But the next morning, with Ki sub gone, Jin woo goes to his room and sees he was right about his window being unable to close. He then feels guilty.
Meanwhile, Ki sub seeks help from Balg um, trying to understand what it means to be someone’s ideal type. He wants to see if he can be Jin woo’s type. Balg um explains it to him but tells him that someone like Jin woo wouldn’t want to be with him because he’s a play boy. That night, Jin woo brings out the red shoe Ki sub had given him. Just then, he gets a message from Ki sub telling him he has something for him. Ki sub enters bringing with him pork cutlets which he wants Jin woo to eat on his own asking why he won’t confess after he brought him tasty food but Jin woo refuses, telling him he doesn’t like pork cutlets.
Ki sub suddenly starts coughing and Jin woo thinks it’s from catching a cold last night and apologises to him for not caring. He’s hesitant to check Ki Sub’s temperature for fever but Ki sub grabs his hand and places it on his forehead. It’s hot and Ki sub thinks his stomach ache is from drinking the expired milk in the fridge last night. Jin woo scolds him for that. Ki sub then asks if Stomach ache is accompanied with his heart pounding. He tells him his heart is racing and checks the heart monitor on his wrist and it keeps increasing. (Man doesn’t know he’s falling)
Bothered by this, Jin woo rushes out to buy some things for him while Ki Sub uses the opportunity to go through Jin woo’s stuffs and check if there’s something he would find that can help him determine Jin woo’s ideal type. He then notices some cute stars and ornaments that Jin woo obviously cherishes. Meanwhile, Balg um notices Jin woo rushing out of a convenience store with plenty of shopping bags. He wonders what could be going on. While Ki sub has come across Jin woo’s journal which seems empty but in the middle of the note, Ki Sub’s name is written but crossed out.
As soon as Jin woo returns, Ki sub asks him why he crossed him out but Jin woo is angry he went through his things. However, Ki Sub is more interested in getting his name uncrossed and becoming Jin woo’s ideal type that he even writes a contract, telling Jin woo that if he doesn’t become his ideal type in a week’s time, he would leave the house. Jin woo accepts the challenge. He then wishes him good night and Jin woo leaves while Ki Sub goes through the many things Jin woo bought for him. Meanwhile, Jin woo lingers behind the door longer until the lights go off. But as he’s heading out to his own room, he sees the moon, stars and several ornaments hung up beautifully on the ceiling. Ki Sub did it and in that moment, Jin Woo hears Ki Sub’s heart monitor rising. The two are both in different places but it’s as if they are attuned to each other.
Meanwhile, Balg um is surprised to find a young handsome man waiting in front of his house. This man is Ji in ho and he tells Balg um that he will sleep with him tomorrow…
