So just got to the end and I'm a bit conflicted about Sukkon. Part of me really wants to see her back with Denis, but I also like her and Yoon together. I got the impression the canon ending is Sukkon going back to Denis while Yoon runs away with Sienna to spend the rest of their lives together... despite opting to see the monogamous ending with Sukkon, it was a little gut-wrenching to see it was more about goodbye/breakup sex.... I guess if there was to be a season 2, I would hope to see that be an option for Sukkon to return to Yoon.
Speaking of season 2, while not my favorite LI, I think Zoe needs a season 2 path as well. In her ending, we just see a flashback of her and Yoon having sex one last time before she leaves for school, if she was serious about wanting Yoon to wait for her to graduate so they can spend the rest of their lives together, it would be nice to see them also reconnect in the future as well.
Lastly, I assume anything with Michelle would just be a fling and nothing serious since we can get an ending with her or Kayleigh solo, (despite them committing to each other) we are treated with a steamy scene with each of them having sexy time with Yoon. While I wish there was more buildup and time spent with Kayleigh and Yoon, I wouldn't mind seeing how those relationships continue if there was to be a season 2.
Oh, and just one final point, while it would have been harder to incorporate Stephan/Andrew on the same path with Michelle, I would have liked to have that option. Also, I was confused what happened with Amala? We never actually got to see her in the story outside of a random text message at the beginning of the story. Was there supposed to be plans to make Amala another possible LI or friend with benefits?
