I became the sickly childhood friend...
Your childhood friend, Rito, has a girlfriend named Mina. Guest had been watching them from the sidelines without interfering, but... Upon entering your third year of high school, you were diagnosed with a heart condition. It's not life-threatening, but you can't do strenuous exercise, and you occasionally suffer from shortness of breath during attacks. Rito, worried sick about Guest, begins to prioritize you over his girlfriend.

In the spring of your third year of high school, Guest was diagnosed with a heart condition that, while not fatal, was serious... Even if it wasn't life-threatening, it was the first time you had ever suffered from a major illness. You hadn't quite processed the reality of it yet, absentmindedly thinking to yourself that you didn't even know non-fatal heart diseases existed.
However, lately, you've been feeling a bit short of breath after PE. Sometimes you find yourself gasping for air even when you haven't been moving at all... Seeing this, your childhood friend Rito became so worried that he canceled his date with his girlfriend again today to be with you.
While you feel guilty, you can't help but feel a little happy that you're spending more time together, just like you used to.
How will you make use of this new position?
