Okay so I've seen many comments abt
"Wasn't he younger than blah blah blah"
Or
"Their age gap wasn't it 2 years?"
Those were just scattered memories and the ages of course weren't out in order, for that reason because their just minor memories or encounters, but yes their age gap was two years,
Another thing that I read in the comments was
"That's not a first kiss"
Since they're children, they obviously don't understand the "first kiss rule" which is why jeongguk accuses Sana of stealing his first kiss although it was on the cheek
If there's something you're still confused abt pls tell me, and I'll answer them
