These are 2 series I love reading and are really comedic~ (You can find any series I post on mangago)
Otouto ja Irarenai!! by Minaduki Yuu
Plot - Kai loves his stepbrother Riku from the bottom of his heart. However, Riku treasures “the bonds of siblinghood” more than anything, so Kai must hide his feelings and instead act as a “good brother”… but skinship no longer satisfies him anymore! I just LOVE sibling yaoi love, it's so cute to read, and this is no exception to that! This is really cute, the other characters involving the story are extremely funny aswell and add to the story and it's just another general great read!
Gakuen Keiji Love Mission by Amagi Reno

This is just an hilariously cute yaoi series. The seme is so lucky and cute and the uke is so cute with his behaviour. If you want anything cute but different, you should definitely check this out!
