1. Love moves in mysterious ways.
At the start of the film, lead stars Carlo Aquino and Bela Padilla find themselves sharing more than just a table in a coffee shop one rainy evening. Their instant chemistry and unexpectedly good conversation about love and life gets drawn out into that one perfectly innocent night with a good-looking stranger.
2. Fate will make you wait.
After their picture perfect night, the two characters only cross paths again four years later in a different coffee shop, both of them looking a little wiser, but not necessarily better. This fateful encounter has them feeling more drawn to each other than they will admit and only confirms whatever feelings that had lingered when they first met.
3. One encounter is all it takes to fall.
While it is only later in the film that their true feelings for each other are really revealed, their fleeting encounters are enough to create a huge impact on each other's lives even if they never fully acknowledge it to each other whenever they meet. Whether real or imagined, they have become each other's ideal partner.
4. You can never deny what you really feel.
Carlo Aquino's character Jessie is a former rock singer turned veterinarian, a man who has decided to totally turn his back on the arts. But every time he meets Celeste (Bela Padilla), she becomes a reminder of the passion for something he thought he had already lost. This is also why one of the most memorable scenes in the movie is when he finally gives in to his feelings for her despite the consequences of his actions.
5. You don't always need a happy ending to have a good love story.
All in all, Meet me in St. Gallen doesn't seem to want to romanticize true love nor does it want to highlight how broken and fragile human emotions can really be. What the movie simply wants to do is tell a story of love between two perfectly imperfect people whose lives intersect and who are just trying to make their way through life the best way that they can.
