There's many layers of NTR here lmao. She loves her senpai but the yarichin blackmails her. Her CHF neighbor likes her so he joins her but still feels cucked by the end it turns out her senpai knows it all but lets it happen because he also got cucked by MH's father in law who is the culprit from grooming her into a pushover yeswoman who lets people have sex with her by praising her.
