And now, i can finally talk about this.
I guess Yurea love points is close to 80/100, MC do a lot of things to make her happy, but sometime he make her angry too, a perfect (?) balance.
But sword girl...he only make her happy everytime, i predict her affection points will go near 200, and she will turn full yandere, trying to kill Yurea.
Kinda obvious, this affection points thing will probably be very important later.
