I'm thinking the author makes Taehan change eye colors to reflect his emotions? Taehan eyes change only when he's surprised, angry, or aroused.
I agree with this but I also want to add that I think it only happens when it's anything that has to do with Doyun
taehan's eyes changed colors :0 what triggered this reaction though? i saw the raws and it keeps changing but can't remember if they changed on previous chapters too:(
