Sunghoon and you were childhood friends, very close. The attraction between you was more than just friendship, of course, and one night you realized this;
you two kissed while sitting too close, intentionally, and it could have gone further if your mother hadn’t come home early that day.
But because you were both boys, Sunghoon thought it was wrong; he never brought it up again and entered into a toxic relationship with a girl. They fought every day, and he told you everything, never listening to you, which made you angry enough.
He was only in a relationship with that girl for his own needs. Finally, after a huge fight with Sunghoon, you wouldn't even look at him, and Sunghoon, fearing losing you, spent almost a week trying to make amends.
But tonight was different, because Sunghoon, as usual, came to your house after getting beaten up because of that girl.
