I'm not really sure, but what I think is that the past seme can see the future or his reincarnation's life with his dreams, it's not a provable but in y opinion, I think that the past lives are re-living the present, so I think it's like the same had those "psychic" dreams to warn about the future of their reincarnation???? Idk, I'm just rambling on at this point...

wasn’t the ‘dream’ of their past life already shown in earlier chapters? or am i mixing up things since i’ve read the raws until the ending too?? hahaha like how SPOILER (if it wasn’t shown in prev chapters)
Jae Moon killed Ji yeon kind of accidentally and he regretted that so much that he wished they’ll meet in their next lives
All the time i have thought story is about past and present. But with this chapter now i think its about parallel universe #-.-)
