i'll be specific because I want to rant sorry

. mc is questioning his feelings because he's starting to look forward to having sex with black haired girl which shows the depth of his feelings. teacher is annoyingly childish and honestly a downright petty btich. she loves shoujo manga, and pretends to be knowledgeable so no wonder her love advice towards black haired girl was so awful, has zero experience in love, and is deciding on whether her feelings for mc is just her overlapping him with her favorite manga character who looks like he's in middle school like really. she will go on a date with him next chapter to try to confirm. and mc declared too that he wants to get to know teacher better at one chapter whether or not that is romantically idk but still scummy while not only is he still cheating, he wants to add one more person to the list when he's already questioning his feelings with arrival of black haired girl. also demon mentions that it's more fun when the "pieces" are higher in number
