Summary:
From Viz media:
Timid and self-conscious high school student Karin never paid much attention to boys until she met Kiriya, a popular student from a nearby boys' school. Karin and Kiriya embark on a romantic journey despite Karin's classmate Yuka's best efforts to sabotage their relationship, but Karin soon learns that living happily ever after isn't on the curriculum when she becomes Kiriya's center of attention, as well as embittered Yuka's bull's-eye on her dartboard of hate.

P.S. (there's 58 chapters in total of this series, but I couldn't find chapters 31+ of Oyasumi-Scans, if anyone knows where I can find them just send me a message and I'll upload them. )
