Name of this BL Webtoon

Set in highschool, the protagonist has white short hair and delinquent look (piercing and alwat agry eyes). He used to be friends or ex lover with the second love interests with dark skin and black hair but after a fight they went to different schools prior the story. This second love interests is very delinquent & violent like.
The story let's say starts with MC falling a bit in love with the male lead (has light brown gair) who is a good boy in school (role model or something) and while attempting to involved the antisocial MC, he ended up falling for MC. The story is shaken by the second love interest (dark skin) who is a transfer student in MC & ML high school. MC ended up going with this second male lead bc the latter threatened to harm ML who remains oblivious and hurt at MC ignoring him.

Pretty much this is what I remember but some extra details:
- it's a Korean webtoon i think or prob Chinese.
- it's completed and has a sequel story
- the characters don't look like teenagers but, like people on their 20s-30s wearing high school uniforms. Anyways they look older and bulky for highschoolers.
