Mo Jun Jie's hearing aid

I don't think it was ever explained. The plot revolving around the murders is always confusing, in fact, I still don't know why Mo Junjie became the suspect in the future where Yunru died.

About hearing aid, the original scriptwriter replies this as NO.11 of "More info" in the following link:

The Korean remake provides the explanation exactly same as I thought, but it is so easy to guess.
So far, I don't believe the original scriptwriter's answer. I guess he must make this part too complicated to make sense. You know that guy really tried to make the script not easy to guess.

You dpon't believe the scriptwiter's answer that it got cut because of time constraints? THAT'S bizarre. It's the simplest and most likely explanation. TW Dramas are always longer than they should be anyway, and every Drama everywhere has scenes cut because of time constraints. Why would you doubt the person who actually wrote the script? They have no reason or motive to lie, which is what you're saying they did.

I thought it was obvious that the reason MJJ was arrested for murder was because he insisted his own guilt. Even helping disguise the crime scene. A confession along with incriminatingly being at the crime scene is often enough to convict someone.  Not to mention this was like during the 90's. 

Poor boy was so in love with that girl and she didn't want to be remembered/forgotten as the "loser girl who eventually died in a loser manner and killed herself because she was a lame loser". She had issues like severe insecurity, poor self esteem, identity crisis and overwhelming social anxiety. So she wanted to be remembered with impact and have her death be declared as a murder. It helped that there had been an actual homicidal stalker after her life. 

Also, I think the cops could've easily been called beforehand by one of the characters - (they did all suspect there to be an actual murder).

Came here looking for that answer too. I guess they just forgot to adress that. Also as soon as she jumps to her death the cops are nearby and ready to arrest Mo Jun Jie. No evidence to convict him. I liked the drama but there's just a few things they could have fleshed out to make it a bit better.
