Nahh, he's jsut an introverted dude tf. I would love to hear your reasonings THO and time and time again, Noa does and is shown numerous times to greatly misintepret nearly everything and get depressed about it.
If anything, Rihito is jsut tired of having to wait for Noa to stop CRYIGN OUT Loud...
The author has been Legit Rage baiting since Noa started getting real clingy.
It used to somewhat be about Noa wanting a close friend but soon became her basically wanting a bf but being too scared to actually call it that.
And yeah, feels like she's just waiting for Rihito to say he loves her...
