That's just because in the beginning of the story the author coloured his eyes light brown, but later (after ch. 12) they changed them to a bluish gray with light brown center. But in ch. 18 they reused panels from ch. 5, hence why we see him in both these colours.
Oh, ok. Good to know
Has anyone noticed how the eyecolor of Mr. Ahn is sometimes brown and sometimes blue?
