Uwasa no Oujisama
Multiple Stories but the main one is probably the one about a princely character and a guy who loves sweets. My preferred one is the couple that are already together.
Kichiku, Encount
A story about a guy who overhears a porn video that a guy on the train is watching. He gets a chub from hearing the vid so the guy propositions him all of a sudden.
Royal Fiancé
This guy quit school and took a housekeeping job from a sus ole man to be able to pay for the hospital wages of his only decent relative, his beloved aunt. Only to find out it was actually an arranged marriage with the world's most untrusting prince made by the old king.
Hina wa Mitsuiro no Koi ni Torawareru
Guy has a thing for his friend who is about to get married so he tries to drown out his sorrows by going to a gay bar where he gets picked up by this super popular dude who ends up being his new boss at work. Poor pacing especially at the beginning. Also, seme was a big jerk lol.
Kareshi Glamorous
About high school students that have been a couple for 3 years and one of them's older brother and his lover.
Hidoku Shinaide
4 stars because Nemu is slowly becoming too girly for me. Not that there's anything wrong with being a girl but more like what's the point of reading a BL if the guy's just like a girl in a shoujo, y'know?
Royal Servant
A story about a guy who becomes a servant for a pureblood that saved him when he was a kid but is now a dick because a servant fucked over his entire family and killed them. GOD. Why is Kyon such a frickin' wuss! My favorite is Sinhan and Karis but I have a feeling that one of them will die or will experience tragedy of some sort because everybody knows that stable relationships in these kinds of stories means one of them has to go.
