I'm not a harem-ending enjoyer, but perhaps this should've been one.
Blondie was not the best girl. You can argue she's the worst girl. If you think so it's just recency bias + plot armor.
She's:
- two faced bitch
- very prideful
- high ego
- possessive
She:
- thinks "normal" MC is loser since they met
- threatened sexual assault in order to blackmail MC into being a slave
- leaves MC's project team for the douche's team
She thinks she's a S but "chad" MC discovers and turns her into M + exhibitionist.
If she ever fell in love with the MC, it was his 'chad' version.
Princess treated rough kind of trope, how dare this loser treat me like this? etc.
But then plot armor happens.
Suddenly MC's heart start beating faster when he sees her? Why? She treated him the worst out of all the girls.
After that MC got lost, and suddenly dolled up blondie appears before him? How tf did she found him?
Somehow her photo on the fucking billboard? Lighting is literally setup to make her as beautiful as possible?
I swear this is lost scene from The Truman Show.
Two faced, prideful bitch is nowhere to be found.
She says she loves "loser" MC. Yes, the "loser" MC she hated in the past.
Aaand they are couple now.
There was no best girl.
Just let him have all the pussy and call it a day.
It would unironically made more sense, then forcing personality shifts out of nowhere.
Imo wasted potential. The Spot Master 2 (with better art)?
