Niji wa Yako ni Kirameku
Two lonely people found each other. They were both shackled by society and found freedom and happiness in each other. Very sweet story
Outcasts Bound by Fate
Exorcist x Yokai. Both are outcasts. Human with the ability to see spirits and a white crow. They find comfort and love in each other
Boku no Papa to Papa no Hanashi
Nothing sad happened yet this is so beautifully written it will bring TEARS to your eyes! The reality of two men adopting a child and trying to bring him up happy and healthy while considering what "normal" is to them
Hakuran no Kemono
Human seme captures rare beast uke to sell his horns and hair for profit to help his village as the next chief. He didn't plan on falling in love on the sweet and innocent uke. Wish this was 100000x longer.
TALIM - Dare mo Shiranai Ryu no Hanashi -
Human seme falls for dragon uke. They even have a kidddddddddddddd I cannot they're so fucking cute
Fukurou no koiwazurai
This mangaka is TOP TIER when it comes to beastman x human love!!!
Furenaide Ritorusuta
Borderline incest because older uke has raised the much younger seme since he was only 8 yo. They're not related by blood, since the seme is the son of the uke's aunt's husband from a previous marriage. A little weird still, but their love is genuine for sure.
Natsume-san wa Hirakaretai
Shit that can only happen in fiction. Uke is heartbroken because his ex told him that he's terrible in bed and they broke up because of it. He decided that he would hire an escort service to practice to become "the best lay in Japan" LOL. The escort he hired happens to be his current hired housekeeper, who's of course a fucking hottie. They genuinely fall in love with each other as the Seme opens the Uke's body up to pleasure while comforting his fears and insecurities.
Junai Nante Shiranewa
Seme has loved the uke since high school and has followed him like a secret stalker ever since. He's surprisingly pure, remaining a complete virgin until he gets to f the uke for the first time. The uke on the other hand is a male escort at night because he's trying to find the perfect partner who will not be turned off by his oversensitivity during sex.
Tonari no Metaller-san
