It's a transmigration BL about how the MC needs to become their white moonlight before leaving each world. I've only read up to two arcs and the first arc is ancient Chinese dynasty and it ended up in a love triangle between his younger brother and his brother's best friend..? The second arc was about how he was the CEO's boyfriend but was doing his job for him as CEO as well and the CEO took his liver to give to his other lover and was trying to hide it from the MC...? I stopped halfway to take a break and I can't find the book anymore QAQ would appreciate any help
