I think the letter is from his father, although I dout he'll be coming to visit. They said that the father was really sick and the reaction of the person who recived the letter didn't give off any sort of feeling that they would also be getting a visit. Also the scene where the child and the adult where looking down as Seungho was saying how he felt like he was back at that time.... I think that was a flashback of Seungho as a child witnessing some kind of upsetting or trumatic scene (I think it might be the death, condemnation or something of his mother or someone really close to him).
So which predictions for the next chapter do you think?
1- We will get more of bed sick Seungho and Nakyum nursing him.
2- We will get tender love making with a soft lover Seungho and lots of blushing Nakyum.
3- Seungho will stay away from Nakyum even more, not hurt him but be cold and distant, no sex
4- Something to do with the smelly hot hobo assassin .. maybe more shirtless fanservice with Jihwa or he finally tries to kill Nakyum
5- The hobo tries to harm Nakyum, Seungho tries to stop him and end up being left for dead in the snow. Jihwa has a fit of remorse and confesses everything.
6- Nakyum disappears and Seungho thinks he run away
7- The letter is from Inhun saying he is coming back.
8- The letter is from Seungho's father and he is coming to visit.
9- Min goes to town and tells everyone that Seungho is in love with a lowborn and Seungho loses his power
I am predicting something like 2 and 6 but maybe we will get more filler scenes with the hobo. I am in minority but I do not want many scenes go wasted on side characters that are not much more than fanservice. It wouldn't be much of a pet peeve if the chapters were as long as they used to be in the first chapters but now it's barely a couple of scenes and the MCs getting stalled just so pointless fanservice for the sake of fanservice just grates the wrong way in a story that is otherwise kept pretty focused.
I hope we get more development between the MCs before too much pages are wasted on side couples or characters, just my wish.
