If you got a soulmate like this, do you...

The anime movie called Your Name,which tells the story of a boy and a girl who are high school students, meeting in a dream and looking for each other. Even in their own dream, their will change their body, more precisely, their soul... Although the process was bumpy, and they forgot each other, finally they found each other again...
I have watched the movie for many times, but I was always in tears... Maybe for their reunion, or for their coupling... I don't know, but I would thought, If I got a soulmate like this, I will find him desperately, and never let him go. After all, it is such a hard-won fate!

And you? What would you do?
