Jaemin's Pitching Practice Behind the Scenes

Why Koreans care

Jaemin says fans had asked him to throw a ceremonial pitch, so he decided to make it look impressive. The footage reveals how seriously he treated that request: he trained twice and worked specifically on holding his finishing position so the ball would travel straight.

In the Korean comments

One commenter says this was their first baseball game and that, despite not knowing the rules, they stayed to cheer for Kiwoom after Jaemin’s pitch and watched him become a “winning fairy”—fan shorthand for a guest whose team wins on the day they attend.

What the words mean

The title’s “차원이 달라병 걸림” (chawoni dalla-byeong geollim) literally means “caught the ‘on another level’ disease.” It is playful, exaggerated fan slang: the uploader has become so impressed by Jaemin’s pitching that they cannot stop treating it as exceptional. A comment connects the wording to an earlier Jisung version and finds the matching titles cute.
