I totally agree, Ive read a ton of omegaverse and I think it's either imprinting or bonding. I mean Taeju could just be one of those guys that likes a good sniff outta the person he likes but the fact that he's been getting anxious when Euihyuns not around and now Euihyun is also starting to get anxious without Taeju seems to be pointing at the fact that the both of them might've imprinted/bonded with the other without each other noticing it. Plus with this latest chapter with Taeju coming home and immediately settling Euihyun into a hug just to breathe and take him in and Euihyun anxiety washing away instantly during that settles it with me imo
Why do I getting the feeling that both of them already imprinted each other as in already a pair without needing to bite gland..?
