Reality just slapped him in the face hard.
They were in a bubble of falling for each other and it made everything seem simple but almost getting pregnant when Doyun can't even control his pheromones is a wake up call that they can't be this reckless. Taehan as the experienced alpha has a certain level of responsibility to guide Doyun through things he's unfamiliar with. Doyun didn't know what knotting was. To get a guy pregnant when he didn't even know HOW that was possible must be weighing heavily on Taehan. Nothing with Doyun is simple and he needs to figure out how to be a good and proper alpha to him.
Taehan still loves Doyun but he is just shocked.
I agree with this observation and opinion. Taehan is not really being a jerk. Y'all ppl in the comment section judging him as of you know how worst he felt atm.
I said it tho. "I know in my heart that it really is IMPOSSIBLE for them to break up. Its just my mind that is confusing me." And i agree with the other reply. Reality slaps his face really hard.
Taehan looks... it looks like he lost his love for doyun. Well, they really love each other and lovey-dovey couple. Its impossible for them to break apart because they can't live without each others warmth but the look on his face confuse me. Is he dissappointed? Is he happy? Is he sad? Is that some kind of poker face? Well. Idk. And I KNOW TO MY HEART, IT REALLY IS IMPOSSIBLE FOR THEM TO BREAK UP. ITS JUST MY FCKING MIND THAT IS CONFUSING ME.
