RenRen's manga / #Twins(4)

Uke considers himself to be the gloomy, less significant twin, and uses his twin’s name while having one night stands because he rejects his own existence and envies his brother’s. Then comes the seme, older, more patient and very kinda. Seme helps him out of genuine concern at first, but quickly falls for him. Seme waits for their friendship to blossom into love because he realizes uke needs to learn to love himself before he can truly love someone else

Wow very good looking characters. Threesome. Uke is awesome for being able to handle both. Most siblings 3-some have the same premise so this one is not unique either

Cousin x Cousin. The misunderstanding was unnecessary. Seme finds that the Uke is the most adorable when he is slightly hurt by him paying attention to his twin sister. They could've gotten together much sooner and saved the Uke from all the insecurities if the Seme just admit that he likes the younger bro all along. Won't re-read again....
