[Nino_izm (2no.)] Jidori Kanojo - SELFIE GIRL Soushuhen + Jidori Kanojo Kikkake Hen [Digital]

This looks really, really good. Thanks for laying the outlines of the story, Ershin

The final chapter is a prequel showing how they met. She's never been very expressive and has trouble being understood. He runs into her on a train and he strikes up a conversation about how she's going to school during the summer, too. She replies that it's for career counseling, and with a smile he proudly announces he's going for supplementary classes. She starts laughing becuse you're not supposed to say that so cheerfully, but tries not to show it and at first he's worried he's made her feel awkward, but powers through it. They exchange contact info and that evening she texts asking his name, and the mad lad fucking calls her on the phone. She freaks out at first, but comes to realize that even though she always felt like text was the best way to communicate, with Kazuma it's different. After he asks if he can call her again and she says yes, he thinks to himself that she's nothing like the girls he knows (his school friends).

In the third chapter they (shockingly) don't go to college together, but they keep their relationship going and graduate and get jobs. Kazuma's job is exhausting and he has no energy after work and develops a form of ED. Airi has no idea about the second part, but is lonely and sad and wonders if they can go back to the way they used to be, which leads to the genius idea that if they have sex he'll get better. It sorta works? They go on a date the next day and she uploads a video of Kazuma and realizes that she tends to get more likes when he's involved, and he considers becoming a youtuber. He gives it a shot, and in the final frame remarks that he's the one hooked on (video) selfies now.

In the second chapter he goes and visits her at a school festival, but his friends come with him and they're very touchy-feely so Airi is jealous. She runs all the way to the girls' changing room and he follows her in and overhears Airi's friends talking about how inappropriately affectionate his friends were being. He realizes "oh yeah hey maybe that shit isn't cool in front of my literal girlfriend" and they talk it out and sexy times ensue. They say they'll keep talking about issues together, and he says he wants to go to the same college as her since they're in different schools right now. When they get back to the classroom, Airi's friends have talked to Kazuma's friends, and they are very apologetic and say they want to be friends and exchange contact info. She mentions that Kazuma wants to get into the same college and they're like "lol look at this" and send a picture of his grades. He didn't even reach a combined 100 in all classes. (He dumb)

Not about to translate the whole fucking thing, but this was pretty cute and came out like 5 years ago with no translation (unless it got purged) so here's a half-assed summary. The title of the series is Jidori Kanojo (Selfie Girlfriend) In the first chapter, they've been a couple for 2 months without even kissing. After a fun date, he takes her to a hotel (and is surprised when she is okay with it), but she falls asleep while he's bathing. He was showering with the assumption that she was DTF, but when she falls asleep he gets worried that his affection is more one-sided than he thought. They talk it out and then sexy times ensue. Afterwards they go to a cafe and get pancakes and he feels like he's starting to understand her a little better.
