Yep and that’s actually addressed in the manhwa. Keep in mind she doesn’t know he’s 10 years younger than her. But it’s not brushed under the rug and it’s treated like the serious thing it is
Not to mention they're probably using the Korean age system which works very differently from the international age system. They're already considered 1 when born and turn a year older every new year regardless of what month you're born. So the 20 year old in this story could actually be 18 irl. Yikes
No, he would be at least 19.
Nah he could be 18 depending on his birth month. For example if he was born on the later months like December, he's 1 when he's born then he turns 2 on a mere month later on January making it +2 years from his original age
25 and 30 is vastly different than 20 and 30, never mind the fact hes still in highschool technically. Maybe cultural differences in my perspective
