Lol, this totally captures what happened between our two leads (If they had actually met at some random set of steps at the end, I would've laughed and done a pump fist). Man, I haven't watched Kimi no Nawa in a while; I might rewatch it sometime.
Yep, not surprising on the mix-up there. If this coffee shop is like Starbucks, it's easy to mix up the locations. At least we can give the trio some credit for being more proactive in trying to help; they failed here, but their subsequent attempts will hopefully be more helpful.
Hopefully, in the near future, Hikoichi and Nayu can exchange contact info. That way, they can meet up whenever and also chat at night when they have some time.
