It's kind of funny how in this and recent chapters there is a bit of a point that Rihito should reach out to his family more now that he lives away, and it is true Noa took (devoured) more of his time he would spend at home, like during Christmas. And maybe if he kept in contact, it would make Reni tone it down and Noa learn to either be alone without turning into an anxious mess or spend time with her gal friend (Nene? The only normal woman in this manga anyway).
But at the same time, Reni and Noa act 100% intense all the time, making it tiring to interact with them and thus Rihito having less desire to contact. So it's a two-way street, he should be in contact a bit more (not every day, twice a week is fine), but also the people who want him to contact them should calm the fuck down.
The worst thing is how Noa of all people is at least self-aware of what she's doing (even if it starts the whole self-loathing cycle), Reni does not see at all how her behavior drives away her brother (helped along by Mika enabling her worst habits).
Once again, please stage an intervention so they get some goddamn meds.
