@YutoKurenai Honestly, it’s not just because she’s pretty, it's also bc there’s way more to her character. Chiaki is basically a hidden genius, a super smart, comes from a rich family, and notices details that everyone else completely misses.
But she intentionally hides her intellect and acts like a cheerful, average girl just because she wants a normal, peaceful school life. That hidden depth and mystery make her the perfect match for y/n. They share the exact same mindset, which gives them a unique dynamic he just can't get with any of the other girls....
