Correct is a matter of opinion… Personally I hate romances between mentors/surrogate parents and their wards in general, with the 10+ years of age gap (regardless of any reincarnation induced “but she’s really an adult in mind” stuff) making it even worse. And having the two pretty much outright disgusted with the thought of marrying each other even now, less than three full volumes before the end isn’t exactly making me any more excited for them getting together either. :/
