This Theory that Piseang is dead could be true but I hope it isn't and that definitely would be one theory to explain Kawi's reaction to seeing Piseang again.
However, I have another theory that Piseang is not dead and that the reason why Kawi was so frightened to lose Piseang because of a scene at 2:23 in the trailer where Pisaeng said to Kawi "If you follow me again I will vanish from your life for good", and I think this scene will occur after Kawi drunkenly kissed him again at the end of episode 7. So I think Kawi might have over the years drunkenly kissed Piseang more than once and made Piseang hope. And that might explain why he left for a year he might have had enough of Kawi denying his feeling and keeping him on a string (Max did say to Kawi you have hurt him enough in Ep 7).
So my theory is that when Kawi found him and drunk kissed him and made him hope again he felt angry at Kawi and at himself, so he finally had enough and told him to leave him and never to search for him or he will disappear from his life. So this can explain why Kawi was panicking about not seeing Piseang again, and the glass globe might not work or might be lost so which will double and triple Kawi's fear of never seeing Kawi's again.
But that is only my theory (and it could be wrong) of what will happen in episode 8 so we will wait and see ;)

Yes, you have a point but there is a chance that he might also be talking to Kawi because my theory is that when Kawi returns to the past (in Ep 8 teaser) he said to past Pisaeng "I thought I will never see you again" and hugged him tightly, so I think the reason he did that because he felt so frightened to lose Piseang because of this scene at 2:23 that I mentioned before where Pisaeng said to Kawi "If you follow me again I will vanish from your life for good", and I think this scene will occur after the Kawi drunkenly kissed him again at the end of episode 7. So I think Kawi might have over the years drunkenly kissed Piseang more than once and made Piseang hope. And that might explain why he left for a year he might have had enough of Kawi denying his feeling and keeping him on a string (Max did say to Kawi you have hurt him enough in ep 7).

After re-watching the trailer. I think in episode 8 we are going to get lots of interesting scenes that were shown in the trailer so I think we will get the scene at 2:34 when Piseang drunkenly tries to kiss Kawi and Kawi stops him with his hand, We also might get the scene at 2:23 in the trailer where Piseang tells Kawi not to follow him again or he will disappear from his life for good.
We also might get the scene where Kawi and his dad are talking at the hospital scene at 1:28
We also might get the scene where Kawi and Piseang are in Kawai's room and Piseang is half naked. So we will wait and see what will happen ;)

I agree, and when I re- watched the trailer I also noticed that we might get in episode 8 the scene in the trailer at 2:23 where Piseang tells Kawi not to follow him again or that he will vanish from his life, and this scene is also done while they were camping so I think this scene will occur after the kiss at the end of episode 7.
Also, I think in the scene in the trailer at 1:29 where Kawi and his dad are at the hospital talking so I think when Kawi returns to the past his father will still be alive after the surgery, and for a minute I was afraid that he already died in the past because of how Piseang was desperately searching for Kawi to tell him something before he vanished to the past. So he still didn't die so Kawi might still have a chance to stop his dad's death.
Also, I think the scene in the trailer at 2:14 (where Kawi is wearing the grey T-shirt that he was wearing when he told him to date him in the episode 8 teaser) where Piseang was half naked in his room, so something might happen :)

No, I don't think so I think they changed it from the novel and I have a theory that Kawi said to past Pisaeng "I thought I will never see you again" because if u re-watch the trailer there is a scene at 2:23 where Pisaeng said to Kawi "If you follow me again I will vanish from your life for good" and if u notice the background it is the trailer were Piseang was camping so I think this scene will occur after the Kawi drunkenly kissed him again at the end of episode 7. So I think Kawi might have had time over the years drunkenly kissed Piseang and made him always hope Piseang leaving could be that he had enough of Kawi's hot and cold behavior leaving him always hanging on a string, so when he found him again and kissed him drunkenly again he finally had enough and told him to leave him and never to come back and I think when he tried to go to the past to fix everything the ball was not working so he thought that he will never be able to see Piseang again and panicked that is why when he returns to the past Kawi hugs Piseang tightly and tells him that he thought he will never see him again. That is only my theory of what will happen in episode 8 so we will wait and see ;)
