Well it depends with the genes I guess. I’m already 33 but I get mistaken as a student and most of the time always given student discounts. When I got pregnant at 30 they thought I was 13 and I was like I’m already 30. I’m already in a high risk pregnancy because of my age (Got pregnant with my first baby pretty late lol ) Trivia women’s egg cell declines it’s quality as we age, that’s why it gets harder to get pregnant and when you do it sometimes get miscarried or can result to a high risk pregnancy. Anyways, when me and my fiancee goes to a hotel they always ask for my ID. My fiancee got conscious so we stopped going to hotels hahaha. He also looks younger than his age about early 20-ish but he’s the same age as me, it’s just that I look way younger than him so you get the idea.
Of course, in real life exists every type of human proportions, looks can be deceiving, and it's valid. But in fiction, it's a conscious decision when the artists determine how some characters will look like. Everything has a meaning so yeah, Jeonsu looking like that and changing so much, while funny and I get why he's drawn like that, I can't help feeling the ick when he's too child-like. Especially when they're intimate. Not complaning, just an observation.

I love them but the inconsistency of Jeonsu's body proportions takes me back a bit. He's just too small sometimes, almost child-like. But yeah, he's an adult and him being small, the size difference, it's part of the charm in their dynamic. Anyway, lovely chapter.
