Vast is the only one who can make Silvia felt like home when they are both away from home. Although he is not the romantic type of guy, being in a relationship, Vast knows how to show his love through actions not words, one time is when he took care of Silvia when she was sick while in Shanghai.
Spending time together in 3 years, understanding each other, these two knew they'd found someone special to their heart. Vast simply proposed to Silvia to be part of his remaining life by passing the ring in a chili sauce box and Silvia already understand the meaning of his action.
Seeing how well Vast treats Silvia, once, we caught sight of how women deserve to be loved.
