Asanagi Umi, the "second cutest girl in class," and I, Maehara Maki, were talking about a "lovers' trip" ahead of Golden Week.
But since we were high school students, we weren't allowed to travel together yet, so Umi's parents made me a suggestion.
He's going home to his hometown in a hot spring town, and I've decided to go with him!
It's been almost half a year since I started dating Umi.
Since your relationship is going smoothly, shouldn't it be time to take it a step further?
While struggling with such emotions, the two of you take a walk around the hot spring town, play in the river, or go to a mixed-gender open-air bath, and your heart races without stopping?!
On the other hand, the condition of Umine's older brother, Riku, is somewhat strange.
It seems like he has something on his mind after reuniting with his childhood friend Shizuku… … ?
