Thank you for the translation! I feel so bad for the MC ... I hope that the ML realises what he's missing and does something. If you live life too relaxed you're gonna let precious things pass you by!
The female lead has confirmed herself to be a 100% idiotic moron and the 3rd wheel is a scumbag of the first order. The male lead is far better off disassociating himself from someone who jumps to their own conclusions without even bothering to confirm the truth from the person in question. It would sure be nice if she ended up alone after the 3rd wheel gets what he wants out of her and drops her like a lead balloon.
I know there wouldn't be any story without such a misunderstanding but seriously. For two people who used to talk all the time to just stop communicating altogether? Oh, come on!
