Mc probably didn't have a lot of pics growing up as an orphan and so didn't want to get rid of the small memories be it something that annoyed him too. How cute
I also think that this is truly a webtoon that could talk about found family - mc not having a proper guardian to look up to and ml having found another family after losing his sister. I'm genuinely wondering how this is gonna become romance. I hope it doesn't ick me.
but will the blonde guy also end up with mc's ex??
