Too many Loopholes and questions, confusing

First, I'm referring to Manpasikjeok as Flute for easier typing.

This had the potential to be great but too many loopholes, questions. Episodes 1 to 12 were good even with the unnecessary Jumps from one scene to another. Episodes were understandable even with Sudden switches from Corea to Korea. but from episodes 13 onwards it started to get really confusing especially if you watched 10 episodes in one sitting. It gave me headache to process everything. Too many JUMPS from one scene to another. Maybe bad editing/sequecing. Any websites which can help me understand? Like after the first time LG travelled back to 1994, how was he able to travel from that 1994 to different timelines and get back to the present day with only half of the flute in hand? Plus wearing the same clothes during the whole time. What was the disappearing plant meant when Jung Tae Eul woke up from a nap on her desk? In what time line was it when JTE was interrogating Luna was it before LEe Gon cameback or after? And what's the point of that? Filler? Also I thought they can only travel through different timelines if they have both parts of the flute? LG was only holding half of the flute when he travelled back to 1994 for the second time, he was with Young, since the other half was with Yee Rim. YEE RIM used it to enterthe gate with JTE. Sooo confusing.

What happened to the present lee gon? Like how was he able to travel back to his PRESENT timeline? Did he "steal" the whole/unbroken flute from the 1994 timeline in which he killed the 1994 Yee Rim? If he stole it and brought it to his present timeline, does that mean the "new" 1994 timeline in which he saved didn't have its own flute? The Flute that Lee Gon brought from his own timeline already vanished.

Also when he travelled different present timelines/universes to look for the JTE version that he loved, was he using the Flute from the 1994 timeline? Did he travel through 14,000,605 timelines? Difference between 2020 and 2021 aren't that long, I don't think that's long enough for his search for the correct timeline/universe to Find the right JTE.

Timelines/parallel worlds are complicated.. LEE GON saved his and her timelines but it doesn't mean all other timelines are fixed or according to the fate that they think is right. towards the end they make it appear that "fixing" one timeline fixes all the the timelines/universes. They make it appear so from all the time travels they've been to at the end. Fixed means no BAD GUY Yee Rim.

Since I'm not blinded by my admiration of the Main Leads Lee Min Ho and Kim Go Eun, i think I can honestly say this was not the best. Good but not great IMO. Great acting but really messed up execution in some parts. Don't get me wrong, I really liked episodes 1 to 12 and the last 36mins of episode 16, they really just messed it up at some parts towards the end. I LOVED every moment/scenes that Lee Min Ho and Kim Go Eun were together. They were cute. The last 36mins made all better since it's a happy ending for both. They can make you forget all the confusion from episode 13 to 15 and first 44 mins of episode 16
