Doyak set up a story about escape. - Youngwoo managed to escape and motivated TJ to come away with him.
Doyak promised character growth. - Youngwoo has evolved; his back no longer seems small; he believes he deserves love and, in turn, can give love.
Doyak framed a love triangle as meaningful choice. - She did not in fact abandon that choice, she wanted Youngwoo to freely and bravely make that choice. And that choice is TJ.
