Aino's battle against weight

I am currently playing through Aino’s story, which seems to center on minor side stories meant to allow the player to spend more time with her. The first segment, shown in the attached image, is about her weight. Tsubame suggests that she wear a bunny outfit for an upcoming masked party their friend group is hosting, but the back of the costume breaks while she is trying it on.

Aino interprets this as a sign that she is getting fat because she doesn't work out, sleeps too much, and eats a lot. She begins a journey to lose weight and engage in physical activity, which is quite a disaster for her since she usually sleeps for more than 15 hours a day. Of course, it is not that easy, and Tsubame eventually discovers her eating snacks in the middle of the night.

The second part is related and involves trying to get her to sleep less so she can spend more time with Tsubame. Unfortunately, even reducing her sleep to 11 hours a day leaves her so debilitated that she falls asleep during a swimming test in class and nearly drowns. This leads to a few cute scenes where Tsubame helps her retake the test so she does not fail the class.

These are pretty fun segments, but nothing has really connected to Yua so far, as she is still sleeping in her room in this route. I think I am getting near the end of this story, so let's see if anything else happens.
