How cute. I like this pair (=・ω・=) It would have been better if they got more development, but I kinda like that their only problem is major miscommunication and not a GIANT RED FLAG.
I am also no fan of coffee, but this made me crave it. Which is kinda hard to achieve, because I have been working in a gelato shop with great coffee but I still couldn't warm up to it. I can only enjoy it with a ton of milk, a scoop of ice cream and some hazelnut syrup.
