I would really commend the production and cast of the show since portraying a story within just 4 episodes is really not an easy task especially for the director and the cast who would convey the feelings of their character. Specifically this part of En of Love--Love Mechanics, I personally liked the #VeeMark. In my opinion, VeeMark visuals surpasses the TOSSARA, and there's a lot of emotions being poured by the character so i really commend the talent of War and Yin. The OST are sad, the opening song is sad, the ending song is sad, and Mark is sad :( I'm looking forward for more series that shall come to Mark and Yin. I hope this series becomes a success. I will recommend this.
