Hope she's not just another useless-lesbian-childhood-friend-that-kept-her-feelings-to-herself-and-will-only-now-confess-because-her-oneitis-found-someone-else™.
the friend's reaction is totally justified here, out of the context of a yuri manga this situation is insane and really dangerous.
but from our perspective she's just getting in the way lol
Ya irl I'd be putting Ms. debt collector in jail for grooming... Honestly, Ms. debt collector going to jail and the best friend swooping in to date the MC would be a pretty halarious ending for the manga. Tho it's never going to happen.
