exes where wy was at home when the doorbell rings and then when he opens the door he is surprised to see sn there soaked from the rain and half drunk. he lets sn in because even though they are no longer together they still care a lot about each other.

wy takes care of sn and lets him sleep at his house. the next day, besides having a terrible hangover, sn also caught a cold because of the time he spent in the rain (he walked all the way wy's house in the rain, poor guy).

wy takes care of him and in the meantime they talk and blah blah blah a lot of things happen and they decide to get back together because they still love each other and the reason for their breakup was silly and immature.

im sorry, i watched a soap opera the other day with a similar scene (except for the part where the character wasn't drunk lol) and i couldn't think of anything else but wsn. but you can blame me? they live in my head 24/7 🤷🏻‍♀️
