It's the first manga that comes to mind everytime someone mentions green flag seme to me. But I'm sure you read it already.
Try :
Tameshi ni Komando Itte mita
My Sweet Husky Papa
Leash Me Up
Smyrna and capri
Knock me up (not sure if uke is experienced but he cool)
Monetary love
Tnku for the list. I've read all the other ones except for my sweet husky papa
That's what happens when I get fed up with the inexperienced ukes, red flag semes, rapes and repeated cliches
FACTS ε=ε=(ノ≧∇≦)ノ
I'm gonna keep posting this every other day until I find all the good stories
Idk, if ya have red this but… https://www.mangago.zone/read-manga/title_mitei_no_prologue/
(I like how uke isn’t super pure maiden virgin and actually has experience but is still really cute and innocent to love) (also no rape + seme is actually good guy) (๑•ㅂ•)و✧
I only red this like an hour ago and then thought of this comment, lol
I like it (づ￣ ³￣)づ
Experienced uke and seme + smut + green flag seme + drama + good plot + no rape
Would be nice if its in a college setting
