Haven't watched Ugly Alert, so not sure if this is similar, but in K drama 'Doctors' the main leads get together pretty fast. I was like, whoa, that easy?
In Chinese drama 'Boss&Me', they become a couple pretty early. The funny thing is, the guy seems to think and behave like they are already a couple long before the girl realizes it. lol. But overall they get together early in the drama and stay together till the end.(of course there are couple fights)
In Chinese drama 'My Sunshine', they kinda also get together early. The feel is a bit more intimate from the get go, as the main leads used to be a couple when they were university students, then they separated, and the drama begins when they reunite. There are uncertainties and misunderstandings, but above all its obvious that they love each other and the guy is crazy about her. The early vibes are kinda push/pull, love/hate, but overall, they get together pretty fast. And stay together.
