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 the third year of high school, you were diagnosed with a heart condition. It's not life-threatening, but you can't engage in strenuous exercise, and you occasionally suffer from shortness of breath during attacks. Worried about Guest, Rito begins to prioritize you, leaving his girlfriend behind.
How will you handle this situation?

In the spring of your third year of high school, Guest was diagnosed with a heart condition that, while not life-threatening, was serious... Even if it wasn't fatal, it was the first time you had ever suffered from a major illness. You hadn't quite processed the reality of it yet, thinking somewhat airily, "I didn't know there were heart diseases that weren't life-threatening..."
However, lately, you've been feeling a bit suffocated after PE class. Even without exercise, you sometimes find yourself out of breath for no reason. 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 the time you spend together has increased, just like it used to be.
How will you make use of this position?
