Tl:dr 'cause some of ya'll apparently can't read more than a few sentences but can read 60+ chapters of gay porn for some reason;
Iheon just wants to clarify if whether the current Huimin is still "alive" or if one of the other two has resurfaced due to current Huimin learning about the alternate timelines. The other two timelines were dead ends so he's terrified that, once again, Huimin is going to die.
YES PLEASE, I'VE BEEN DYING TO EXPLAIN THIS
I apparently live to passive-aggressively explain BL plots in autistic detail lol
I am so unbearably exhausted. The bar is in hell lol
He's asking 'cause one version of Huimin was so broken and disgusted with Iheon he died and created a whole alternate timeline for them.
Then there's the alternate timeline Huimin that was never even allowed to consider a mutual love with Iheon to the point the world stopped when Iheon tried to confess.
Then we have the current Huimin who believed he was isekai'd the entire time and that himself and the Huimin from "Silence" were two different entities till recently. He's also the only version of Huimin that even dared to fight back and work things out with Iheon on equal footing. Granted, part of this was possible due to Iheon trying to do things differently this time around, but Huimin's current personality is still a 180 from the first one. Despite still having the aversion to alpha pheromones, he doesn't cower away or think all alphas are just rapists. Somewhere down the line he genuinely wanted to heal so him and Iheon could actually fall in love and be happy.
Right now Iheon is terrified. He's formed a one-sided dependency on Huimin's pheromones and being away from him is literally killing him. He's panicked 'cause Huimin now remembers that all three versions of him are real and currently a part of him so in Iheon's mind Huimin is going to leave him again. 'Cause why wouldn't he? Iheon was the main source of Huimin's pain and eventual demise their first time around. Of course Huimin would have every right and reason to runaway and never return to Iheon.
This is them meeting and confirming what is going on. No one knows aside from Huimin and us readers what is going on in Huimin's head.
Ya'll are just too dumb or unwilling to actually think for a second to realize *why* Iheon asked that question first. I don't even know why I bother trying to explain shit anymore.
