The suitor in question is often a close friend, confidant, or acquaintance of the lead. Their relationship is often platonic in nature, at first, and when anyone suggests the suitor as a match, the lead may initially dismiss the prospect due to the nature of their interactions. However, eventually, the suitor's relationship with the lead evolves, and the lead begins contemplating what they may have overlooked before.
Perhaps the lead was previously with someone else who wasn't right for them, or even if there wasn't anyone else, perhaps the possibility of being in a romance with the lead hadn't necessarily occurred to the suitor, either. Either way, there needs to be an in-universe justification for why the two end up together.
In any case, once the lead realizes that the suitor is -ahem- suitable for them, there is a high chance that the suitor is the match that the lead has been looking for the whole time.
There can be some crossover with the Dogged Nice Guy, inasmuch as such a character tries to be noticed by someone who previously overlooked them, but the combination of both tropes is not a given.
This plotline is a classic staple of Romantic Comedy, though it can also be found in other places.
While there is some Truth in Television regarding this phenomenon, inasmuch as it is not unheard of for people to begin relationships that they would have previously considered unlikely, there will be No Real Life Examples, Please! Especially since it would involve gossip about the relationships of real people.
Since this is a reveal trope, spoilers will remain unmarked.

- In Naruto, the titular protagonist is initially so emotionally stunted by his upbringing in the village that resulted from his parents' deaths and the way the majority of the villagers treated him because of Kurama that he is completely unable to tell the difference between romantic love and the kind of 'love' one would feel for a favorite treat (such as ramen). And as a result, he proves completely oblivious to how Hinata is just about the only one who genuinely likes (and later loves) him for exactly as he is even back when they were both little kids (and the fact that he also ends up developing a shallow crush on Sakura as a result of him coming to view her as a prize to be won in his rivalry against Sasuke (whom Sakura herself likes) certainly doesn't help either). It isn't until long after he's matured and later realized the true nature of different types of love (among other things) that he finally becomes aware of how Hinata had always been willing and able to give him the love and attention he'd wanted for so long even when no one else would. And from there, the two eventually manage to become an official couple.
