Hajime is a nutcase. It’s just too funny; I really enjoyed how the accusations and suspicions of infidelity were responded to by Mahiru. After a while he just dismissed the somewhat imagined gravity of the situations and sort of humored Hajime by not actually getting angry.
Reading this felt like sitting around and yucking it up with old friends. It was so comfortable and lazy and the things that made me laugh felt like inside jokes. I love Kusama’s casual day to day storytelling.
