In Dear Love, Blueberry is a good friend and best friend of childhood, and they have a very good relationship and talk about everything. Tongnian and blueberry have the same hobby, and they both like singing very much. Blueberry's husband is a gun fan and worships guns very much. The couple also promoted the relationship between Han and the same year and often gave them advice.

In the play Dear, Love, Tong Nian has two good friends, one is Sun Yaya, Tong Nian's roommate and best friend, and the other is Tong Nian's colleague and best friend Blueberry. The Blueberries are the people who want to be with Han the most. They always create opportunities for Han in the same year, but they always help each other, which is very interesting.

Blueberry's husband is a die-hard fan of Gun, and he knows a lot about Gun's season achievements. In order to get close to his idol, he is very supportive of Blueberry and his childhood watching the game in Gun, because the mistakes and logical ending of Blueberry's family have pushed forward the talks between Korea and North Korea in childhood.

Once Tong Nian was drunk, and Gun wanted to send Tong Nian to Blueberry's house. Blueberry jumped with joy, and her husband dressed up quickly, looking forward to seeing his idol. When they received good friends, they didn't rest at home with childlike innocence for the first time, but took out their mobile phones and took photos of themselves, completely forgetting the existence of childlike innocence.
