Same here I had Megane at lvl 2, after completing it the "challenge " button didn't disappear like it usually does , I was able to complete 6 challenges in a row without spending any affection points , I think I could have gotten to lvl 9 if I didn't go to the office to check if her perks were unlocked (which they were). I currently have her lvl 8 and i play from Nutaku.net
