I understand where both of them are coming from, fear and anxiety are a part of life, but letting it control your every action isn’t good, by the same token neither is it not being taken into consideration. Mei has the unique position of being someone who puts others before herself, and values herself much less than everyone else. It isn’t a good habit of hers, but that’s entirely a her thing. It’s why she’s so nonchalant about danger and doesn’t care to think before doing things for others, she’s no different from Rentarou in that aspect.
Kaho on the other hand is always wracked with self doubt, fearing things she can’t control, and in doing so is always left feeling like she isn’t living her life to the fullest. When in reality she is just dealing with things everyone handles in their own lives. She just feels like something’s wrong with her for feeling the way she does. Her, Tama, and Mei could have an interesting introspective discussion, maybe even get Nano in there for good measure and have Momoha there to mediate.
I feel like they need each other to better themselves, it’s a proper give and take relationship. Everyone really does love each other, and it’s through chapters like these were we really get to see that love shine.
