"Their Wonderful Times" is the story of a girl who is so obsessed with her late brother that she can't accept his death. To keep him close, she creates a video game featuring a character that looks just like her brother, whom she refers to as "brother." A company wants to collaborate with her to launch the game, but a glitch occurs, forcing them to delay the release. The glitch involves the sudden disappearance of the villain character from the game. Eventually, the CEO discovers that the villain has somehow entered the body of the game’s creator, and only when he touches her does she return to normal. As the story progresses, they fall in love.

However, the villain begins to take over her mind, and she starts losing her memory. Although it's just a code from the game, the villain’s influence is so strong that one day it takes full control of her, causing her to lose her identity. In the end, the glitch is fixed, and she returns to normal. However, the story doesn’t end there, and I don’t want to give any spoilers.

I didn’t like the ending. It feels like the drama was made purely for entertainment. The story only became interesting when the villain entered her body, and she started acting like him. Also, if this was her dream, how did she know so much about the CEO's personal life and family? Other than the leads' acting, the supporting cast was underwhelming—they seemed immature, more like college students than professionals.*
