Mr. Fighting is a heartwarming drama that is pretty slice of life (realistic). You will fall in love with the main four cast members easily. The plot is swift and each scene is planned out well and purposefully. The drama focuses on a friendship turn lovers romance plot which isn't the central focus of the drama but does gradually build up over the course of the story. The lighting and overall editing is also well thought out, the color schemes emphasize the emotions of the characters and the mood of the overall drama well. The soundtrack is also very calming and fits well with the drama.
Watched it because of Deng Lun and realized how similar it is to his storyon getting into acting, which made it even more worthwhile to watch. He is such a versatile actor and it shows here. I also loved his chemistry with Ma Sichun and also the guy who played Fu's Father. A must watch. You can take something from this drama to your personal life as well :)
