>>6861840(You) are childhood friends with a cute (and slightly mentally unstable) summer colour festival, she's into a blonde girl who's a vtuber and even joined vtubing to get closer to her, however as times goes on, you realize that said girl wants nothing with your friend and is interested in some guy from her company, you tried to warn matsuri but she gets agressive with you and ends up not speaking with you anymore,after some months she knocks in your door, crying more than you thought humanly possible, saying that you were right and that she got rejected because hoshikawa has gotten a boyfriend, some comfort fluff ensues and matsuri realizes she has deep feelings for you, she starts to get heavily clingy and possessive of you, but never directlys tells you what she is feeling.
I would like if it ended in fluff (potentially nsfw) but getting into a abusive relationship with a menhera would also be nice desu
