im confused, like it's too sudden. when did they find out they wanted each other ???????? ...

i think they both felt something from the first day they met and daiki didn´t complain over that he had to kiss minjoon every morning even thought it was orders from toma´s hehe and daiki must have been hiding it very well (since he is all serious all the time hihi), also daiki wanted minjoon to call him by his first name from day one, since toma´s called minjoon mom you could see that daiki reacted when minjoon called him boss. but i also think daiki felt something even more after what minjoon told the grandfather and how minjoon has been showing that he really cares for toma´s under this time he has been staying there..
