I am one of those who was disappointed when it got cancelled after airing 4 episodes. But was very happy when gagaoolala picked it up and completed.
All the 4 MLs have done a good job in expressing their emotions.

Story: Though a regular story, it has a nice watch value. The start as strangers, becoming friends, then heading to being lovers. The confusion when you find someone who looks like passed away brother, how its overcome. A great touch is showing the life of deaf.

Acting: QL did a great job in not giving up getting what he likes, who he loves although started with a not so good intention. QX- the confusion, the jealousy when he realized he actually like QL was cute and typical😂 TY- The sadness, desperation when he could not communicate and knew LMY only likes him as a brother. LMY- The big confusion, withholding around TY. The comedic part of Turtle as supporting actor was really nice. I would rewatch it again😍
