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 a Big Damn Kiss. A common feature of a Cliffhanger or Season Finale.

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.
