It's interesting because I think early on I believed that tasuku did some immature things, like when he kabedon'd shia san out of nowhere that one time, that can still be seen as immature but now I also think that's just how his mind works.
Tasuku brings an interesting flavor to the rom-com protagonist, cause while their struggles usually come with being too indirect, too shy to express their feelings or something like that - we see here the issues when you become TOO direct. I really like this new portrayal and I wonder if they're other rom-coms that have something similar (I'm not familiar with those if it's actually a more prevalent thing).
