Itou-san by kuraka sui. Seme is hitman and he loves uke very much amd he is very gentle person!

I 2nd "Itou-san" too!! It fits you criteria.
You can also try "Acid Town" and "Usagi otoko tora otoko"(although this one is more on the comedy side than the other two).

Been there done that and loved it !! Thank you though !!!!! ╮(￣▽￣)╭

Ahahahahah theyre BROTHERS .. Like they both came out the same vagina

Ahhh then i'll read itou san .. Im dowloading it right now annnnnnddd I LOVE USAGI OTOKO TORA OTOKO this manga is actually the reason why i asked for reccommendations!!! Ive read it for over 10 times maybe even more and i never got tired of it until recently ... Its beautiful and heart warming thats why i want to find moreeeee !!, and im also dowloading acid town just to check it out .. Thank you !!!

Oh, shit!! Now I am feel guilty for recommending you Itou-san & Acid town :(
You see they are beautiful but not heat warming like usagi otoko. On the contrary they lean more towards the tragic twisted psychological genre. It might even ruin the warm fuzzy feeling you are get after reading usagi otoko. So, I thought I should let you know beforehand.

Fyou jerk !!!!!!!!!!!! Im crying right now !!!!! I just finished itousan !!!!! How could you !!!!!!!! Im seriously crying with snot running down my nos right now !!!!!! But i loved it !!, so thank you, jerk. Thank you

Im going read acid town tomorrow so i could atleast give myself a break jesus christ ... Your warning was soooooo late im still crying rightnow
Thank you .. Fuck you and i love you,bitch good day

Hah? You also forgot to mention that you read usagi otoko & were looking for something warm & fuzzy, stupid!! Next time try checking the genre before reading the manga, doofus #－.－)

Glad you enjoyed it! Acid town is in it's own league. Hope you enjoy that too...AND BURN IN AGONY FOR UPDATES LIKE ME *muhahahaha* (๑•ㅂ•)و✧
