You can tell how much Geumie loves Taesun. He even thinks his own lifespan doesn't matter and would gladly give all of it so Taesun could stay with them forever. But Taesun doesn't want Geumryang to sacrifice his life either. I can't blame Taesun when he said he should've ignored Geumryang when they first met. Geumryang's life has always been built around transactions. People came to his mountain to exchange something for what they wanted. As their love grew, Taesun stopped seeing it as a transaction, even though Geum still viewed it that way, which is why he felt like he could never love Taesun perfectly. In the end, they're just loving each other so much ╥﹏╥
