Why dandadan is perfect romance anime?

I think main reason is that it feels so natural and it focusses on little thing, like when okarun is really sad when jiji came, momo realises that and quickly tells see you tomorrow. Each character has so much depth. There are many moments like that will put smile on your face. Before watching dandadan i didn't like rommace that much, it felt boring and repetitive. I tried kaguyasama, it was good but not great.Personally Kaguya doesn't feel natural.

Dandadan has scifi touch but that's not main assence, momo and Okaruns relationship is the heart of the show for me.

That why Dandadan is best rommace ever!
