I've heard of people physically cheating on their partners, I've heard of people emotionally cheating on their partners, but I've not heard of people culinarily (is that even a real word?) cheating on their partners. Real life is so much more interesting than any anime or manga. And this is from a guy who's lived equivalencies of Yowamushi Pedal and possibly Detroit Metal City.
As for my haps, nothing beyond the usual: work, fitness, RPGFan, reading, housekeeping, voice over stuff, music, and working on that public speaking side hustle.
