I feel like Baron and Mono are a thing that went unresolved throughout the years and this whole arc will be about the two patching up their relationship and being able to move on mutually from each other.. And I think Lego and Mono will still happen but in a duration of loads of development to come...
The Mc disappears for awhile but I honestly think first he'll solve these two's story and then we'll get to see him with someone too, though I can say that this drags out waay too long without the MC
(but then again this manhwa is called "Someone Else's BL Manhwa" So what did we expect)
I really like the progression of these two, honestly it's fresh to see a romance where they really are discovering their feelings for each other rather than forcing the relationship in like 3 chapters. I know the end of this whole story telling thing is gonna end unhappy, but I do hope the mc can bring them together.
I also find it refreshing that the gay guy isn't in a love triangle for once, I mean I expected at first the two to be fighting over him and I was gonna give up the series but this is a nice surprise (=・ω・=)
