My little pet theory (that has almost no evidence to support it lol) is that Wakana is immune to the mind control effects (maybe she is from a vampire slayer lineage?) so she’s just being herself…
The story is really fluffy and cute, but it gets a bit old as it’s the same schtick every chapter. Everything revolves around others accommodating the MC or bowing to her power.
I’m thinking the new girl already liked the MC and is just pretending to be affected by the potion! It’s been longer than a few minutes since they were playing sports and the new girl already seemed to be pretty nice to the MC in the beginning
