Sweet Devil - [BL]

Misha has always been petty—very, very petty. He pays back the smallest grievances tenfold, and his temper flares up more often than not. So, when Santa Claus sends him back in time as a Christmas gift, he’s hell-bent on tormenting his sister’s boyfriend, the cause of all his suffering. No matter what, he has to drive the jerk away, or else misfortunes will befall his family. But as time goes by, Misha slowly realizes that things are not as he remembers them. Perhaps, everything he knows about his sister’s boyfriend was built on lies. That doesn’t mean he will stop pestering the guy, though. Dumb MC x two-faced ML  (Slow-burn, biased POV, HE)
