Thank you so much :) you always answer my questions so thanks a lot :D
Also I remember a !manga but I can't remember the title ( of course T_T) but it was yaoi, the guys were friends, and always ran into each other every morning while going to work. One of the guys thought it was a coincidence but the other did it on purpose just to see the other guy
