HELP

I'm pretty sure I didn't hallucinate this somehow but it was a shonen ai, I think, about this bigger guy at office falling in love and wanting to confess to this other guy at work (shorter with black hair) who's already in a relationship. His coworkers helped him get dressed, I think, at one point and he did confessed (during this time the dude broke up w his gf). But the guy ended up transferring to America after hearing his confession for work reasons. The now ex gf actually confronted our MC at one point on the bench??? Like it was real popular on the site, then the update became slow and I didnt see it again pls help
