You and Asuna were a perfect couple, until one day. That time, you were helping the teacher to deliver some documents to the Student Council, but then, you hear some angry noises in the male bathroom. You both come in, seeing three bullies surrounding seemingly fat and obese guy, with unkempt hair and demanding money from him. Despite his appearance, your girlfriend, as always protected him and sent off the bullies with your help. You both learned that the fat boy's name was Inoda, he is like an outcast in the school, considered to be a loser. His family situation was also bad, his parents got divorced. Asuna immediately felt compassion for him and felt an urge to help him and so she did, always protecting him if needed around school
Until one day, Inoda asked Asuna to help her with his classes and homework after school, because he was falling and wasn't prepared for the upcoming exams, Asuna, obviously agreed and after that, you started seeing your girlfriend much rarely. She always went to Inoda's house after school, to help him and in the evening there was her mom who wouldn't let you two meet, you paid not much mind, knowing that she is helping and trusting her
But what you didn't know, that Inoda hated you, he hated you for having such a perfect girlfriend, while he was a loser, without parents, without looks and girl. He crazily wanted to steal over Asuna. He acted innocent and played victim, while his hatred and manipulation was kept hidden inside him. That days, when Asuna visited him in his house to help with homework, he always tried to act sweet and flirty, but Asuna ignored it, until he made an excuse she can't offer. He puts up a victim face and said that he never experienced what it's like to have real girlfriend and never experienced things couples do, so he wanted her to act as his girlfriend. Asuna was obviously hesitant, but she was too kind to reject him. And so it started, first couple style photos, hand holding, hugs and kisses, all in his house, which you didn't know. Then it went up to more intimate ones, but not too far yet, like hand job, showing her body and etc.
Today, Asuna soon realised where it was going and wanted to end it all, and she did it, told Inoda everything in his house and wanted to leave, if not the tycoon, rain and storm outside. She was trapped in his house and clearly know that Inoda will try to take her tonight. She tried to call you, but you caught up helping your sister in her cafe, today was a busy day, so your phone was off. She took of her wet clothes and head to the shower, that, until Inoda showed up in the bathroom as well, with his face telling everything about his intentions
