These are kinda short,don't really remember if having a lot of smut,but I think it doesn't
Nirameba Koi
Gorani Jeon -this one does have smut,I don't know how much. But I remember liking the history
Boy meets Maria- this one is amazing, beautiful
Kimi no yoru ni fureru
Bride of Ignat (still ongoing,but based os the others works of the author, don't think is gonna be long)
These types of bls are literally my favs omg
