https://www.mangago.zone/read-manga/short_cake_cake/ this is the better version of this manga btw (shameless promotion of my enjoyed manga)
you are so right, every manga in this style has the same storyline. we don't even need to read this manga to know the entire storyline.
thoses manga are supposed to be "original", a breath of fresh air but no. it's the same thing again and again.
its so disappointing whenever i read a new shoujo and its the same thing all over again. always the age gap, toxic male lead and power imbalance.
i loose interest in new shoujo, i thought this would be another shortcake cake but no, the guy sucks. its not even about the age gap, he just fucking sucks bru
