Possibly? Could also be that he went into heat too and marked the omega (I’m super bad with names...)
ig in love shuttle that happened when the alpha got excited or nervous/anxious and when he was in rut. so im guessing it would be a similar thing..
Some Omegaverse in novels and stories I have read online sometimes incorporate Were-wolf based themes.(⊙…⊙ ) Wherein when an Alpha is in a rut/horny or senses his Omega is being targeted by another Alpha and gets possessive his eyes will change color.
At least based off of this webtoon that is the case I hope this explanation was helpful to you.(★^O^★)
Naw that's just a unique trait of Teahan.

Not saying your wrong with THIS couple(▰˘◡˘▰) as I DO agree with you there on that one, buuuuuut in the raws the first couple's Seme (can't remember his name at the moment) his eyes do end up changing color when a jerk of an Alpha tried to hit on the Omega of the first couple despite the Omega's persistent attempts to refuse him. Then the Seme of the first couple grabs the jerkass alpha's arm in a fit of anger at this causes his eyes change color.ヾ(☆▽☆)
yep yep that's right, I just finished reading the raws. so I was kinda right
Why did he eyes changed colour? Is it like a side effect on him being horny? ⁄(⁄ ⁄·⁄ω⁄·⁄ ⁄)⁄
