That’s the guy with the blue hair who had a crush on MinJoon right? If I had to guess, author probably realized that readers found the conflict annoying and just sent him to the shadow realm, never to be seen or heard from again. You’re right though, that subplot did vanish into thin air. Especially since the character of Kubota’s lover was introduced and it seemed like they would be a mainstay. But this author also likes to resolve conflict in a very short amount of time. Kidnapping drama, attack drama, living somewhere else drama only lasted like 1-2 chapters, when in most other stories it would take like 20 for the main characters to wrap it up. It wouldn’t surprise me if it had nothing to do with reader perception, and the author just didn’t want third wheel Kubota to get in the way and overstay his welcome. Which I love since manhwas become hard to read when every problem in the couple’s way takes 3 months to resolve!
LoL. I was thinking he was already at the bottom of Han river.
^ This is my new headcanon
This is adapted from the light novel with the same name actually. So the mangaka isn't the original author. Kubota didn't exist in the novel at all, it's a character mangaka created and probably couldn't come up with any interesting follow-up with him. Probably dropped him into nile river :v
Does it ever say what happened to Kubota?? I know he was an insert character created by the artist (I think), but like, he just disappears at one point and never gets mentioned again from what I’ve seen. Have I just missed something or did he just get dropped from the story??
