Here, we see the classic "Misunderstanding because a couple won't communicate". I imagine the quality of this depends on how much you enjoy this type of misunderstanding versus how much you cringe at it. In this case, it feels more like a case of awkwardness than intentional misleading, so it clicks as 'cute' more than 'cringe' for me. It does a decent job having amusing characters, so while this isn't groundbreaking, this still managed to squeeze out a smile from me.
My ratings on the series, from best to worst:
1-2, 2-3, 2-4, 2-2, 4-1, 2-1, 1-4, 3-2, 4-2, 3-1, 2-6, 1-5, 3-3, 3-4, 1-3, 2-5, 3-5, 1-1
