I can't imagine what it must've been like for her and the other women to watch their partners/husbands/significant others go to war. I think I would honestly go crazy knowing my bf might never come back to me again. The anxiety, the pain, the heartache - oh mannnnn.
I haven't watched ep 18 yet but in terms of ep 17 - sigh unfortunately, nothing happens to YJX. He is perfectly fine (ew; hate him) while our main leads are suffering. He does not get what's due to him yet...which SUCKS!!
