Ashita, Kimi no Mono ni Shite: More

Yuki, a shy and inconspicuous presence in class, and Hayato, the popular central figure admired by both boys and girls, are lovers.

Due to a small misunderstanding, it took them a while to reach their first intimate moment, but now they can't keep their hands off each other, indulging in passionate encounters every time they meet.

Despite their lovey-dovey relationship, Hayato is concerned about the toll it's taking on Yuki's body. On top of that, they're facing a pile of problems, including career path dilemmas and the risk of Yuki's dad finding out about their relationship.
