This is one very interesting BL manhwa. Now I am more convinced that what happened to the MC at the start of the manga is the same as I initially thought.

I am guessing the gangster is someone the MC was in debt with so he can't easily transfer to another company. However I look at it, ML (the former classmate now model) definitely likes the MC since they were in middle school. My suspicion is the ML thought the MC liked the brown-haired boy in the past so he kissed him to make the MC stay away from the boy but it backfired when MC left him (w/c was mentioned by the ML). In reality, something might have happened to MC's father that caused him to move away w/o telling the blond ML.
