Ah, Summer. For some, it's the season of partying. For others, it's just work with an added dose of hotter temperature. (For us in Sacramento, California; it means deadly heat waves and town-destroying forest fires.)
For Kazuya; it's summer classes, more asses, and wishing Chizuru the best while secretly wanting to see her again.
