In episode 21 of "The Wind Across the Blue Sky", My Anh (Phuong Oanh) continues to find a way to get close to Suong to save the company. By sending their son to study Pickleball, My Anh and Suong were able to confide in each other more. When My Anh showed her how to be friends with her husband's stepchild, Suong honestly said: "Most people think that I am good to him because I am afraid of him, but the truth is that I am no longer capable of being a mother." This secret surprised My Anh.

In another development, Ngan (Viet Hoa) continues to fall in love with Truong (Dennis Dang) - the owner of the yacht where Ngan is on vacation. Truong's delicate gestures moved Ngan.

The relationship between Hoang Lam (Quynh Kool) and his wife has become increasingly cold. Lam is no longer interested in Toan (To Dung)'s work. When Toan said that he might have to go on a 6-month business trip, Lam calmly said that she didn't care and that he could go as long as he wanted.

"The Wind Rings the Blue Sky" episode 21 will air at 8:00 p.m. tonight on VTV3.
