Watashi no Cosmic Monster

From Ikemen Scans: "His expression, his voice, the scent of his skin… though the other party is my older brother, I can't help but desire him. " A playboy college student who doesn't run out of lovers, Jin's stress relief is kissing his foster brother! An ordinary big brother who's adopted, Souji, who plays the good kid and doesn't get angry no matter what is done to him. The only thing that upsets this big brother is the unexpected kiss. The mask of the older brother who never shows his true self was finally peeled off… Or so he thought but… "I have no plans to cut ties with you, Aniki." Jin raged when Souji suddenly said he's moving out!? He tied up his resisting older brother and stirred his tongue inside his flaming mouth. Huh? It's strange…? He can't stop getting excited by everything about Souji… A sadistic type yandere (sweet and gentle yet brutal) younger brother x kojirase (someone who's not confident about their self) type ill-fated older brother, and their forbidden-obsessive love!!

Tsubaki, who places an importance on "being cute," picks up a strange fluffy creature and brings it home with her. She brings it into the bath and it transformed into a naked boy?! What is going on? Is Tsubaki going to live with "Fuwa" (as in Fluffy) the alien boy??!!

Yuki and Hayato are brothers that live alone in a run-down apartment. They were very close in the past, but now Yuki has distanced himself and Hayato doesn't know why. A dramatic story of two brothers with a twist.
