Don’t ask how SS knew BB is leaving the village and where to look for her, he just does.
I will follow you wherever you may go. There isn't an ocean too deep, a mountain so high it can keep me away. I must follow you
In bottom middle pix, Bing Bing is still looking at the site where she last saw SS but unbeknownst to her, SS has jumped down from the other side of the bridge onto her boat. Only when she feels the boat rock did she realize that SS is somehow on the boat beside her. haha! BB is beyond shock to see SS on her boat.
So consumed by fear of losing BB that SS did not even hesitate to jump off the bridge onto the boat to stop her from leaving him. When he landed he immediately beeline towards BB and grabs her into his arms, holding her tight, stilling her struggles.
A bittersweet moment for BB to be in SS' arms (again or first time?). SS smiles in relief as he holds her tightly in his arms. He has found her!
But SS's moment of sweetness is quickly cut short when a teary eyed BB berates him for making the parting even harder for her with his presence. Let me go, let me go!
"I won't!" says SS, petulantly.
BB desperately tries to make him understand her pov. "Don't you understand?"
"No, I DON'T understand!" says SS in frustration.
"I also don't understand you saying your leaving is for my own good, you think by leaving I'll forget you?" says SS in exasperation, his eyes filled with hurt and accusation
SS: You truly want to leave? The sorrow on BB's face mirrors the pain in her heart.
SS: Fine, you push me into the river... then you can leave Even mature men like SS are allowed their moments of childish tantrum too.
BB: You're an idiot, if I push you into the river won't I be worried to death? How can I leave then? And spunky women like BB are allowed their occasional irrational but heartfelt responses!
SS: So, why do you want to leave?
And then SS gives the perfect speech of wherever you go I'll follow you. Whatever happen we will face it together. Don't talk about you sacrificing for me or I sacrificing for you. Ok? Ok?
And finally BB cracks an acquiescing smile , and her smile makes SS smile too, knowing that everything is fine now between them.
SS pulls the smiling and crying BB into his arms. He chides: Don't cry! Not allow to cry!
GAU DIM! SS successfully wins the fair lady's heart back!
All's well that ends well. At this moment in time, SS is the happiest man on earth, and BB, the happiest woman on earth despite her tears.
