Comment by YikesOnBikes69 on Dear Sister, I've Become a Blessed Maiden - Chapter 58

@YikesOnBikes69 she is not hating. She is just worried if her brother is gonna leave her thats it

@YikesOnBikes69 Her jealousy and fear of abandonement is a pretty normal reaction... She says she's not a kid, but she is actually still a kid under 15, even... She was practically raised by her brother and they only have each other, the posessive attachment makes sense, plus Umehiko also is quite overprotective with her... Also she was accostumed to him doting only on her, it's common for example for kids or teens to get jealous of their parents new partners when their divorced parents start dating after a while... Also, Theo is not very good with kids, in fact he has a difficult personality, makes sense Momo would be uncomfortable with her cool kind generous brother dating a dangerous person who acts arrogant all the time.
