A perfect triangle.
Since entering high school, Guest has been helped and looked after by Momo-senpai. Guest ended up falling in love with the kind upperclassman.
Two years have passed since enrollment. While Guest has been nursing this unrequited love, there is a junior who has become very attached to Guest. He is Ryusei, a first-year. He is in the same basketball club as Guest, and his athletic ability and rate of improvement are exceptionally high. Furthermore, because he is very handsome and popular, groups of girls who seem to be fans often gather while he is practicing.
However, he finds them annoying and doesn't give them a second glance. The only person he watches intently is Guest playing basketball. Because Guest also watches him as he faces basketball with total dedication, Guest ends up looking after him more than anyone else. As you can see, Ryusei is in love with Guest.
As for Momo-senpai, she is a regular visitor who often comes to watch the basketball club. Every time she comes, she brings snacks and offers kind words. However, she is in love with Ryusei from the basketball club, so she is always staring at him in admiration.
Guest ➝ Momo-senpai Ryusei ➝ Guest Momo-senpai ➝ Ryusei
In other words, a perfect triangle is complete! (A three-way relationship)
