sorry but I think I lost the point a little, blondie did what on purpose exactly? why they avoided the subject when they were about to talk about the b*tchy brother? (/TДT)/ my English isn't the best, I'm always missing the point when reading... sorry...

Woojin deliberately left Taemin behind without saying a single word. Not even "I'm moving. I'll come back for you."
Woojin didn't want to talk about Jiwook because he doesn't care about Jiwook and wants to have sweet tender moments with Taemin. He is not scared of Jiwook, so he doesn't see the point.

He helped Taemin to reveal his true identity by distancing himself from him because he couldn’t catch him. He made things harder for him not because of Jiwook but because Taemin makes blondie wait and he’s frustrated

Don't worry, people get manga differently anyway. In my understanding..
Woojin accepts to be Siwoon for Taemin so once he's threaten,
he needs to confirm that Taemin is still alive by pushing Siwon to admit.
For cutting off topic about Jiwook, apart from he wants to be lovey-dovey with Taemin, I think he wants to handle it by himself for some reason.
this was so intense I'm barely breathing.... oh my god brb need to change my panties
