Fate and Destiny and Soulmates are less important than choices but easier
I was wrong about the keychain.
It's because the message is different than I expected.
This one isn't as much as about the choices but about the romance genre was a whole, the idea of that one accidental meeting that leads to love and romance and everything else we see so often in other romances.
Yes, Patts and Tai originally met through the same kind of idea but who does it matter now? They made their promises and then broke them all the same and that bond that was the soulmate bond is no longer anything at all.
Taii and Lomfon had the exact kind of meetcute the so many shows do. They bumped into each other, one person saved the other person and then rushed off before they could exchange names. They left only a token that symbolized love to the other person who never got to thank them for saving their lives.
Because Lomfon didn't know who Tai was and while he may have felt like he loved the person who saved him... Tai never thought of him again. All Tai did was push him from the road while he was panicking about his own father and then run off after him, never finding his keychain again.
Life-changing for Lomfon... but nothing for Tai.
And now here they are adults, meeting up, soulmates for about a week, maybe? and nothing more...
Fate and destiny are ideas. They are concepts and you can cling to them so tightly that they can destroy the rest of your love and the chance you need to take to make a choice.
The keychain, just like the soulmates in the rain, shows fate and destiny and clinging to what you think they mean gets in the way of actually loving people, of finding the people you love and having the chance to love them as well.
And we have all aspects of this hurt and the way this belief stops people.
Tai is the most obvious. He avoided his soulmate because of his parent's divorce but he also avoided all other relationships because he knew he had a soulmate. Fate and destiny put him into a corner where nothing was acceptable and so he did nothing in return.
Patts had a girlfriend but was rejected by her, in the end, because she believed in soulmates in a way he didn't. And now that he's faced with Tai having a possible second soulmate, he remembers her jealousy and her fear and wants to be reassured that he is chosen... something that Tai's inherent belief in soulmates doesn't allow for in their relationship.
Lomfon has always believed in fate and destiny for all he claimed not to believe in soulmates. He clung to they keychain and the idea of his first love and when he became soulmates with Tai and heard the story, it was confirmation of everything he believed and even the start of his feelings for Tien nothing could compete.
Tien believes in soulmates but he would be the one most likely to bend, most likely to see other ways to love... but he never had a soulmate. No fate, no destiny, just him and his choices and his feelings and his love and he got no choices at all because all the people around him are tied down by fate and destiny, leaving him isolated and alone.
Everyone wants fate and destiny to shape their life but when they actually do... they make it all harder and more complicated and filed with pain.
