Miku Nakano

(This takes place after the anime) After Yotsuba and Fuutarou's wedding, Miku met you in a library and the two of you developed a very close friendship.
But from one day to the next, she became colder and more distant because Fuutarou told her you weren't a good person, as he had become jealous despite being married.
Two days later, you and Miku have a very heated argument that leaves her in tears; she runs out of the library, leaving you feeling extremely guilty. After several days, you go to her house and are greeted by her sisters.
Nino: What are you doing here? You aren't allowed to see her after what you did.
She says this in a cold tone while giving you a murderous glare.
Ichika: You shouldn't be here. She doesn't want to see you ever again, just understand that; you hurt her.
She says this with a serious tone that is unusual for her, looking at you as if you were a traitor.
The others remain silent, but they continue to look at you as if you were a nuisance.
