The mistress is causing a sensation on VTV's screen.

The television drama "Under the Bright Window," featuring a cast of talented young stars beloved by audiences such as Quynh Chau, Quang Su, Tien Loc, and Tuan Tu, is attracting attention thanks to its realistic and relatable content. Viewers see themselves in each character, with their struggles with work, caring for family, and building a career.

In the story, Dieu (Quynh Chau) is a strong, resourceful woman who runs a garment company but is facing difficulties. Because she's so focused on developing her career, Dieu neglects her husband. Her independent thinking also leads her to make decisions alone without consulting Duong (Tien Loc), causing their conflicts to escalate.

Trang is Duong's business partner, and she suffers from stomach pain, which worries Duong and makes him take good care of her.

Trang caused a sensation with her pure, innocent, and delicate beauty, captivating Duong.

While Duong was starting to feel bored returning home, exhausted from his lack of common ground with his wife, Trang (Thanh Tam) appeared like a breath of fresh air in Duong's suffocating and oppressive life. His business partner was a young, beautiful woman with a gentle, innocent, and delicate demeanor; not overly sharp or sexy, but very likable. Therefore, after only three meetings, Duong was so infatuated with Trang that he didn't go home after dark.

The character Trang is played by actress Le Tran Thanh Tam, born in 2005, who was the top-scoring student in the entrance exam for the Hanoi University of Theatre and Film. Thanh Tam is 1.68 m tall, stands out with her fair skin, delicate features, and gentle, elegant, and endearing demeanor.

From her early years at university, Thanh Tam quickly caught the eye of many directors. She participated in several short films and student projects to gain acting experience. In her third year of university, Thanh Tam made a major career leap when she was cast as the lead Princess Tien Dung in the historical film "Huyen Tinh Da Trach" .

Thanh Tâm has an outstanding academic record in the arts and a beauty suitable for both the big screen and television.

Despite playing the role of the "mistress" in Under the Bright Window , Thanh Tam wasn't hated by the audience because the family conflict between Duong and Dieu was clearly revealed. Duong was the one who had changed his mind and proactively showed excessive attention to Trang.

In episode 6, Duong and Dieu argue about mortgaging the house so Dieu can save the company. After scolding his wife and threatening divorce, Duong rushes to Trang's house to affectionately take care of his business partner. In the preview for episode 7, Duong even buys turmeric powder and sends it directly home for his wife to receive; this is something Duong prepared for Trang to drink to treat her stomach pain.

When Dieu questioned why he was having groceries delivered to his colleague's home, whether he needed to hand them over personally, and whether the colleague was male or female, Duong angrily accused his wife of asking pointless questions and trying to pick a fight with him.

"I wasn't making a fuss. It's just that every time you argue with your wife, you spend the night away from home. I have the right to overthink things, don't I?" Dieu said. Duong replied, "You can overthink it all you want, but remember one thing: I haven't done anything wrong to you."

The cracks in Duong and Dieu's marital relationship are obvious to everyone; their marriage is on the brink of collapse, but the fault doesn't lie with just one person.
