Thank you kind spoiler person. 
This chapter was so . Poor Namwoo... i can't even b all that upset as Sieon cuz he's really done nothing wrong to Namwoo tbh... he just wants a diff type of relationship than what the MC wants.
Those last few panels w the red head dude and Namwoo's ex-crush are giving all sorts of red flags already. I also hope that Namwoo's ex-crush doesn't turn out an a*s. He looked nice so far but reading BL/yaoi has given me severe trust issues lol.                                            
                                                augghhgeidhfkahdgdfj and this is the last chapter of season 1 so now we have to stew in the angst until season 2 comes out (╯°Д °)╯╧╧

apparently?? the red head is Si-eon's ex boyfriend??? I neeeeed season 2 out already, I think we're going to get some clarification of Si-eon's past and why he is the way that he is.                                            

		
Namwoo meet up with his sister in a Cafe, they had a pretty light hearted chat and the conversation was very funny. The sister's boo already sold out in market and the sister explained to namwoo how the characters in the book represents her and namwoo's relationship... the cover of the book was had a picture of a girl healing a dragon... (it was so funny omg). And namwoo asked how does this represents him. His sister explained that in this book at last they both mend their relationship by love and understanding each other which she also wants in their relationship. They left the Cafe and the sister asked if namwoo wants to go with her for dinner and that bearded man aka si eon's fried will also be there but namwoo said no since he thought it's will be awkward for him. The sister teased namwoo a bit calling namwoo brother -ah ... and namwoo was like do you have no shame ?? The sister said it's fun to embrass him .
Now back to si-eon and namwoo proposal scene , since si eon only said thank you as a response namwoo asked "is that all ? Thank you is all you gonna say?" And si eon replied " perhaps..." then namwoo asked " are you angry about the earlier situation ? If that is the reason then please let me apologize to you about earlier ." Si eon replied that it is not that and he could never hate namwoo for that. And his feeling for namwoo is same as the first time nanwoo puzzled ask " first time ? I thought si eon had the Similar feelings for me" . Then nam woo asked " I don't understand why do you keep meeting ?" ( I do not understand si eon's reply of this particular question from namwio so I will just quote it as it translates ) si eon replied " what fell earlier was caught in my hand " , namwoo then asked " do you not like me ? " on that so eon said " I like you but it's a pity that I can not return your feelings , and for this if you wanna leave me I will understand . It's for namwoo to choose". Then si eon finally asked " what you wanna do ?" And namwoo replied " I don't know"
Now in the dinner scene between namwoo's sister and that bearded man , they were talking about very trival things so I won't add them here the only one thing note worthy was that the bearded man told the sister how si eon accepts every situation in life and moves on from it.
Now in Las three panels we can see namwoo's ex crush smoking , and talking with a red haired dude. The crush asked the red haied man if it's cold and the man replied I like cold . ( they look like they are up to no good ,lol )
