Jiang Li Sun's Links
His boyfriend,
He's deeply in love with him, even if he rarely can say 'I love you' without a curse behind. (being a tsundere) He always puts Ushi's safety and well-being before anything else, as he's really heartbroken when he sees him down.
The only time he didn't do so led them to some horrible events for them and it's the biggest regret he has up until now, so he promised to himself he won't ever do that and will definitely bring happiness to Ushi.
His boyfriend. They are always swearing to each other because of their thug attitude but that's a characteristic of their peculiar love. Even though he doesn't really show it because of his detached façade, he's the most important person for him in his life. He's ready to compromise many important things for him with no regrets and will always be grateful towards Jiang for having helped him giving up on drugs.
