Auuugh they really do need to have a good mother-son talk sometime!

As for CR notes, Litchi just. Adores Kazuma. He's a reminder of home, surprisingly without any guilt attached despite how much he looks like Hazama. She thinks he's the cutest thing ever, but she sorely wishes he took better care of himself. (Although many people say the same of her.) He's pretty much her son in her mind.
