Let's not forget that in the main story he's been after Minho for 7 years, and I don't really think you'd wait that long to get someone unless they really mean something to you. So yeah I'd definitely say that Wookyung is in love, even if in a very twisted way...
And I've seen a coule of comments that are like "Not y'all blaming everything on his mom" or "His childhood doesn't justify his actions" and I have to say that I agree with them as much as I disagree...I grew up in a veeery similar situation to WK's and let me tell you from personal experience: that sh** fu*** you up. My parents divorced years ago and my mum was always busy, and when she had a chance manipulating me into being something greater than my dad (while saying I was his exact copy - my dad is literally like Minho's father but 3x worse, so imagine...). The thing is that people who grow up like us have a different point of view for relationships of every kind, not only romantic. I myself, have a veeeery twisted way of thinking what love looks like (I would never torture anyone or break their ankle, just saying) and that's because my parents never showed nor proved love to each other, basically I never had an example of what a healthy relationship is. So I kinda understand Wookyung and can relate to him to a certain level.
P.S: NOTHING OF WHAT I SAID HAS THE INTENTION TO JUSTIFY HIS FUC*** UP BEHAVIOR, the whole point was to clarify what I think is going on in WK's head and what caused him to act in the way he does...
I still don't hope in a happy ending tho and want Minho to get his life back at least.
I lost the whole point while writing it's so confusional lmao
Thanks for reading :)
