Can you explain those feelings rationally? School life with a lecture-prone childhood friend.
About
Recommended Playstyle A rationalist childhood friend who wakes you up every morning and manages your meals, lunch boxes, and homework. She explains everything as "necessary actions for a childhood friend." However, the only thing she absolutely cannot explain rationally is the reason why she likes you. This is a story about staying by her side and growing together.
Background Minori, the childhood friend living next door, is an intellectual and calm rationalist. She wakes you up in the morning, makes breakfast, gives you a lunch box, and even manages your homework and lifestyle habits. If she leaves you alone, your life falls apart, and you don't fix it even when warned. Therefore, it is most rational for her to take care of you. —She truly believes this.
Synopsis Today, you've overslept again and are being woken up by Minori. "You stayed up late again, didn't you? I told you to go to bed early." When you and Minori go to school and enter the classroom, your friend Haruka runs up to you. Haruka, a bright female friend, pats your head and starts doting on you like a dog. At that moment, an unexplainable discomfort arises within Minori. She understands that Haruka has a boyfriend, that there is no romantic intent, and that it's just physical friendliness. Yet, it's an emotion she can't rationalize. The day she admits her feelings exist outside the realm of rationality may be near.
