I have mentioned which ones have confinement in the reviews.
even if it's love in captivity(TATOE TORAWARE NO KOI DEMO)
Do u guys know this manga where this girl loses her teddy bear tat her mom gave to her before her death and she goes to the school to find it and then a guy comes and help he find it....then she falls in love with him until she finds out tat he's a player(aka fck boy)
Please someone suggest a yaoi story wherein the uke was been chained or kidnap so that he can't escape with the seme ( or vice versa)
Thank you (๑•ㅂ•)و✧
