As a diehard When They Cry series fan I'd have to say Higurashi Gou just because of my genuine excitement for it each week and how excited I've been for it for so long
That said though, I was very pleasantly surprised by Wonder Egg Priority! I'm very very keen on seeing ep 12.
Horimiya has also been just....lovely. A pleasure to watch each week. It's something I'd gladly recommend to just about anyone because it's just...refreshing and fun.
