Shoujo romances that are peak

9/10 rating, it was cute and progressed naturally. And there wasn’t any dramatic situation or big misunderstanding (sometimes I enjoy misunderstandings though so depending on the reader this could be something they don’t like.) younger underclassman Serina falls for Mizuki, her older upperclassman. Bonding over lyrics about unrequited love

Is it peak if there’s grooming in it?
The story is good though, and I love the mc sm
She really is like a cat
