i dont think its stupidity, i think its the overthinking and doubting of intentions that leads to miscommunication. when a person likes someone they rarely just open up and tell them, they wanna make sure the feelings are mutual so that they dont get rejected. liking someone is an uncomfortable place to be when you are unsure of the other persons feelings and being unsure often leads to assumptions an doubt. its very realistic to me. there have been plenty of situations that both have seen to make them doubt the other and so both are afraid of exposing their feelings cuz they dont wanna be hurt. i think this has been really well done and is very in line with how normal people would think/react, and whats a manga without a little drama?
The amount of fucking stupidity here is amazing like apparently fucking COMMUNICATING like normal people has gone out the window. Now all we do is make crazy assumptions and jump to conclusions- great.
