A teapot is a symbol of prosperity, the realization that hopelessness can turn back into hope. That sometimes good can come from seemingly insignificant events.
Guen Tae is still not a huge fan of "smelly" tea, but he's a big fan of his wife's joy, happy to see her this excited and is delighted with her sales as well. A sign that placing more confidence in Yunho is something more people should do; she's talented and more than capable after all.
They are kept pretty busy, but yet they still now have a baby boy, a child born out of their love for one another.
And Yunho was so excited to have a baby, delighted to have a little life to nurture, to watch their boy grow. And Guen Tae, maybe he's gone somewhat soft too, because he can't help but adore the little tike too, and want to be a dad that his son will be proud of. Or maybe the real word is strong not soft, a sort of inner strength, a desire to be the kind of man that can be looked up to.
Their love story did not start with tea, no matter how floral, and even in the hard times, they loved one another, but yet it's a wonder, a source of awe for Guen Tae that his wife gets to live her dream and do so well at it.
And he's just really happy for her, and so, so happy too. Life is finally looking up in the Earth Tribe, and even Guen Tae is excited for his son to grow up in a thriving land, for him to hold onto wonderful memories of their kingdom alive and well, the memories of it had gotten Guen Tae through the worst of it, and he hopes that his son will know of a well off Earth Tribe always.
This little miracle definitely deserves the brightest future he can hold.
