Full story isn't out yet, only about 20 episodes...
Spoliers (more like summarized)
Uke is ophan sent to seme 1 's(didn't appear yet) father who is (pedo) and you know shits happened to him, and he wants to revenge but that man suddenly died. So he decided to revenge his son by uncovering all those things. Seme 2 (appears in ch1) is helping uke to revenge (but actually no, red flag lmao) and uke got close to seme1 to get evidences and blah blah the plot goes on.
I don't want to say all cuz this only have 1 episode here. The plot is interesting and the smug scenes are not bad at all.
Seme1 seems to be a green flag at the moment.
I finished up to Chinese site and this is good I recommend. Emotional rollercoaster ahead tho
