@rarelambo21 he isn't. the question was if an outsider could/should be worried by the relationship when they first learn of it. from the outside perspective of a character within the manga's universe, this is an inherently sketchy relationship.
this chapter is only partially about determining if the relationship is sketch, it's more about showing that Gyaru has two good friends around her to keep her in check
lmao yall are sitting here salty that her friend is groping her but they're friends. You can accuse her when she's doing it to random people, but she's well within her right to call a random dude in his mid 20's talking to her high schooler friend sketchy.
