At this point they are more like an old married couple

Nah old married couples bicker all the time they haven't reached that stage yet

Oh i don't mean the kind that bickers all the time. More so the ones so in sync with each other and have a relaxed vibes that nothing can get in between them

i know right omg it's really refreshing to see in a high school romance manga .. their relationship is so full of kindness and respect for each other nd they actually communicate it's so peak
