Did the first couple had potential? They had not defined the relationship at all. The 1st lead could have plainly set a boundary that, no my friend is the devil and I want us to be mutual.
Instead he just silently watched on as his best friend flirted with his partner.
Be faithful to someone who is not willing to name a relationship often leaves people waiting for commitment for years to decades.

I would’ve preferred if he had ended up rejecting Zetty instead of them being a throuple.. but whatever. I’ll take what I can get, I guess *sigh*
