Top five sub-genre that I want to see more

• A finds that their lover B think of them as substitutes of C, who are oblivious/uninterested in B. A kicks B off and gets together with C because C is awesome.
• A gets together with powerful amoral/immoral supernatural beings, (e.g.eldritch god/demon/etc), who remain inhuman and dangerous despite (or because of) how loving they are.
• Rebirth novels that acknowledges that the reborn person still suffers from psychological trauma from their past life and illustrate their path of recovery and setback
• Characters lose something (health/status/etc) forever, but still manage to adapt and begin a new life.
• A is a player who needs to fake being a NPC in mmorpg, infinite flow setting, etc, and maintain the facade, or vice versa: NPC who pretend to be players for survival.

I will really appreciate any recommendations! :)
