Some awfully cute shit. Something so real about the way they fell into it. One of the best and most justified student x teacher stories. Especially considering he was a couple years after graduation and well past 18
Edit: Love this. Very genuine love between them. Haruchika gave Kiyomasa a place to belong to, and Kiyomasa loved Chika forever, in return. I love how tender they both are, in different ways. From Kiyomasa doing everything to prolong Chika's life (he is several years older than Kiyomasa), including cooking healthy mealsband making sure he eats, to how carefully and tenderly Chika opens him up, to how much thought they put into just, everything. Very impressive.
