I remember buying the first volume in middle school during one of those book sales.
It, or some manga about twin sisters going to private school in the middle of some forest that was haunted or cursed when it came to twins or some shit were, i think, the first manga i'd ever read.
Nothing, It's just that I always shit on shoujo for all using the same generic shitty tropes and then enjoy Skip Beat, which, while doesn't use many of them, still plays some straight. Also it moves at a snail's pace and I feel like I'll never see the ending of the manga in my lifetime.
The combination of cute boys + rainbow lighting/sparkles had me sold. Though to be fair, the side materials give it a little more substance.
Pet Girl of Sakurasou. Objectively I know it's bad and the MC is an impotent fuck who is vying for autism-chan, but it just makes me smile
