Diary of a Female Lead: Shujinkou Nikki manga volume 3 features story and art by Yuu Yoshinaga.

When Aoi's family goes on a glamping trip over summer vacation, it could be the opportunity Aoi needs to sort out her growing feelings for Sena. That is, until her mom invites Sena to come along! Being in such close proximity with Sena is the last thing flustered Aoi needs, but it might be an opportunity for the two to grow closer before a class seat change tears them apart again. Maybe Aoi's new seatmate, a cool, gorgeous girl with rumors swirling around her, will distract her from heartache for a bit?
