Yea they are probably not the same person. It would be super lame if they were...I'd probably stop reading it.
from what i read in the raws *spoiler alertttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttt* it seems that when they were still in school together they had sex n the bathroom and someone over heard and recorded them and exposed him. that was about what i got from it. i dont know what happened to the sunbae after but it seemed like he was doing some shady shit with other guys before?
They could be related.... or not lol
mc's sunbae probably abused and betrayed him in the past. some people are thinking that the baker and sunbae are the same person which doesnt even seem realistic considering the bakers family got weirdly involved, if anything, since the sunbae and baker looked alike they could be related/ are relatives
