Yandai Byway is an overall good watch with a well paced storyline and good actors. The chemistry between the actors is amazing, which helps draw the attention and investment of viewers into the series. Although quite disappointed, I did enjoy the ending as the phenomenal performance delivered by Gong Zheng (Hang Hang), paired with the perfect use of instrumental music, helped set the scene. The series delves into a theme rarely touched by other shows in the genre (BL) and successfully delivers an entertaining piece worth watching.
I personally have rewatched the final episode multiple times, caught in awe at the amazing acting and emotion present in the final scene.
