If you've kept up with this series, you know the author updates once a month just about. Sometimes less. So maybe 12 updates a year or less. Not sure why people are so obsessed with the idea that something has to end because... because time has passed, I guess? Too much time has passed = something shouldn't exist anymore?
It's fine to not want to read something, but a love triangle implies there's a choice to be made, or that there are two relationships happening simultaneously. There is one established relationship, and an antagonist who will presumably try to get in the way of that. The hilarity will I assume be him continuing to hit on Yiyoung in front of Kang because he's ignorant to their relationship
