It's sometimes like that though most of the older siblings I know have a much taller younger brother or sister. Even if they're 15 some can hit their growth spurt at an earlier age than most
My youngest sister is much taller than me (I guess 20+ cm taller)
And this year she's just 16 and I'm 20
thank u for the reply! i found it a bit odd since in manhwas they rarely show tall younger siblings hahaha
oohh i see, thank u for the reply!
how come his little brother is taller than him? His littler brother has is below 15 years old
