I couldn't even root for the MC since bro legit cheated on her constantly, there isn't a single scene where he tells her and she doesn't even know how many women this dude had sex with.
Look we can pretend he is a "victim" but even i as a femboy would never let women use me like that ever...
I mean she could play along with what happened by doing the following
1. "Oh nooo, someone tried to murder me! But I hit my head and my personality changed" (make up a reason you survived poisoning)
2. Be kind and very regretful
3. Profit??
