Kang Chi the Beginning (Gu Family Book), Teardrop Kiss in the Forest (Episode 17)

Finally, the long-awaited kiss that GFB fans have been waiting for. Magical teardrop kiss in the forest, surrounded with gorgeous blue lights - Kang Chi aka beast Kang Chi finally broke down after he realized that Yeo Wool is the most important person for him and without her, he doesn't have any reason to live. Yeo Wool is the reason why he wants to become fully human and he wants to protect her from Wol Ryung.

I find the scene really beautiful and poignant. Feel upset for Wol Ryung too as he watched his own son receives unconditional love from Yeo Wool, it reminds him of his tragic love story with Seo Hwa. Unfortunately, Seo Hwa couldn't accept beast Wol Ryung. While Yeo Wool accepts Kang Chi as who he is, beast or human; she'll be there for him.

It's so heartwarming to see beast Kang Chi slowly turns into a human as he kisses her. Love conquers all.

“To be fully seen by somebody, then, and be loved anyhow - this is a human offering that can border on miraculous.”  - Elizabeth Gilbert -

Btw, I really love the newest OST! I think it's 4Men, and I can't wait for the song to be released. 
Update: it is indeed 4Men. The OST (rough title: You're the One / Only You) will be released at noon today.
