It's not just you
Hes still ..rude..but to me it's implied even that personality wasn't his true self it was a negative response to the issues of his family/father but now he realized he could breakdown and be authentic and accepted by jiho so his personality is morphing. Hes not suddenly HONEST he lied about no umbrellas so easily to jiho and is still rude. Hes just changing a bit coz hes found someone whose accepting him authentically
I love how the story is so funny and cute right now but I can’t get over the fact that jihos personality took a 180 so fast. I understand character development but he went from pushing kids minding their own business and wanting to go down on that girls older brother to a flushed face lover boy tsundere for our boy. It could just be me nitpicking even though I have completely NO right to do so but I dunno.
