So far, this feels like a mini-version of
Happy Negative Marriage.

If she always is close to him how did she find the time to find another guy or is she just planning to bait the MC? I think it's the former but who knows. I have this feeling that the other guy is a family friend but the engagement real
It's pretty hard to believe that, if she was so close with another guy that they would get engaged, that the MC would never have heard of him before, after all, they've known each other for six years. And you're right, if she's been sticking to the MC like glue the whole time, when did she get to know another guy so intimately. You're probably right about the engagement being real, and the other guy a family friend. But, if so, it still doesn't explain why the MC has never heard of him before.
