Show, Don't Tell is a main rule of all fiction, visual or not, and applies even more so in emotionally-charged moments of triumph and heartwarming that are seen as having a duty to be as vivid and narratively satisfying as possible to make the audience cheer with glee. Since the Relationship Upgrade in successful romance almost always qualifies for this, there's a strong tendency for characters to act out the moment of upgrade with a big, uncomplicated smooch.
Often, especially in Unresolved Sexual Tension (and its cousins Belligerent Sexual Tension and Love Epiphany), this is a couple's very first time kissing each other, but this is not always the case. It is, however, often portrayed as the couple's first "real" kiss, meaning it can be the first romantic kiss between two characters that have previously kissed due to other motives, the kiss that marks the moment when two exes reconcile, when a casual dating situation turns into true love, or when a couple that has made some motions towards romance in the past finally become a real couple.
A major staple of TV shows.
Compare Relationship Upgrade, They Do, Love Epiphany, Love Confession. Almost always a Hollywood Kiss, and when it's not, it's usually a subversion. Frequently The Big Damn Kiss. A common feature of a Cliffhanger or Season Finale.
- On the very last page of Bakuman。 Mashiro and Azuki finally have their first kiss.
- Fairy Tail: after 200 chapters of beating around the bush when not separated by various circumstances, Erza and Jellal kiss at last! Well, probably... after that Jellal makes up a lie about being already engaged because he doesn't think he has the right to love anyone. Erza doesn't buy it but pretends to. So maybe it doesn't count after all.

It's their second kiss on Chirstmas Eve (which is much more normal) that truly marks their Relationship Upgrade. The actual Love Confession that the whole series was building up to doesn't happen until two days after that during their first date, but by that point it's merely become a formality.

It also turned out to be a Last Kiss due to Kamina dying in the ensuing battle.
Kamina: When we return, I'll pay you back ten times over. Remember that.
Yoko: Couldn't you have put that a little more romantically?

"Not as good as this one," said Carol, and kissed him hard on the mouth.
When they broke, Gladiator regarded her quizzically. "You are right. That is a more proper zone of intimacy."

- If there's any doubt as to how the love triangle in Catching Fire will turn out that ends when Katniss shares one of these with Peeta. On the beach, no less. It turns into a full-blown make-out session that only ends when they're interrupted by a bolt of lightning. Make of that what you will...
- Animorphs: Jake and Cassie finally kiss in #26 after Jake returns from what everyone thought was a deadly fall (he managed to morph a bird midair).

- Yarudora series vol.2: Kisetsu o Dakishimete has straight, subverted, and averted examples:
- Played straight with Mayu: the kiss she and the protagonist share at the climax of the game, after the Race for Your Love sequence, is a True Love's Kiss that not only cement their love, but also revives Mayu's memories.
- Subverted with Tomoko: she and the protagonist share their first and crucial kiss mid-way in the game, and the kiss sequence's symbolic animation is similar to Mayu's; but the storyline after this sequence will pit you with several bad choices that can break the Relationship Upgrade and provoke Bad Endings. If you pick the good choices, there will be a second kiss between Tomoko and the protagonist during the climax of the game: that kiss will definitely solidify their relationship, as Tomoko will finally have overcome her Clingy Jealous Girl tendencies.
