Ugh, it always sucks when a good read ends. Heres looking forward to the next Riichi joint.
That said, I actually really liked how it did start overwhelmingly with the "Oh Shit Hot Mom Awkward Aaaa" and transitioned to Ninomae Slowly but consistently. Like i see a couple people saying it kinda came out of nowhere and was sudden, but from my reading (and maybe it makes a difference of time cause i could see reading it all at once being a very different experience) it seemed kinda obvious where it was going really early on with them and it was more a slow build up on one or both of their parts.
By the time it started being real overt I'd been cheering them on for well over half the manga at minimum, but eh.
Either way, a great cozy read.
