My rating: 5/10
It's not my cup of tea but I understand why people like it. The uke dislikes himself and therefore can't like anyone else. He's kinda gloomy and has a brother complex leading to his destructive behaviour. The seme is a nice guy teaching him about love.
TWINS, PROSTITUTION
The uke feels unloved bc his outgoing twin brother always gets all the attention and others ask him to be like him. So the uke starts selling his body letting his clients call him by his brother's name to punish them both. But then a friendly older guy shows up asking to be his friend.
