Giver: Fukushu no Zoyosha (2018)

Both are about an "revenge agency" of sorts, where a customer can make a deal to have revenge taken on someone who wronged them. One has more fantasy elements and comes with more consequences, but the topic is similar and both are episodic.

Both dramas has the revenge trope. A client will contact the "revenger" tell his/her story then the "revenger" will plan out how the revenge will happen.

A drama about revenge service done by specialists: they help victims to seek revenge on their offenders.
