It’s only said that he sleeps around and we see the “post sleeping” part, other than that he moves to his grandma’s place and meets ML who is also a highschooler right away
Spoiler:
He is traumatized because his first crush said homophobic stuff to MC when MC confessed he liked guys and his parents are neglectful, MC and ML only kissed so far and spoke about wanting to go further

Is there rape/sa here?
