@Nomys sorry for being late, i had to read a few more chapter just to confirm.
That would be about 10%(but i would like very much that she talks again(like she is about to do now), because we get to see the way she talking and a little more of her, that will increase the times to 1.000.000.000 XD)
The 40% of the reason is that she doesn't Nag/Limit/Stop the MC of doing his adventures.
The other 50% is that she actually helps him in his adventures and everyday life, that's how the main girl should act.
Helping the MC no matter if is in the dungeon, in the fields or at home, heck she even says that she is fine even if she doesn't end up with him and just wanna be by his side.(that will be crime if that happens)
