I didn’t know earlier that true beauty’s writer wrote this drama as well. I understand now why there were soo many similarities and even the order of certain events was same. The love triangle plot and the bad boy 2nd lead, Male lead being her saviour and all.
I want to mention some comedy scenes that were cheap and not funny e.g when ML doesn’t hold the bathroom door for a guy and he is exposed among all and FL’s friend pooped in her pants etc . I don’t understand why they degrade the supporting characters like that. These scenes were not funny they were just disgusting.

Female lead was super annoying, she was confused as hell. Made dumb choices and at times i didn’t feel like rooting for her at all. I wanted to tell the ML to just run away from her as she creates unnecessary trouble. She acts from the beginning as she is his girlfriend and not a fan bcz what fans act this way !!!
ML was attractive up to the point he had ambition other than being in love with the FL but it felt like his life revolved around her only. It made him uninteresting.
Episodes towards the end were boring, I lost interest after episode 9. Time travel become boring after she traveled back again and again. Not to mention watching ML die soo many times. And the show didn’t pick up from that point and goes further down.
Music was amazing. The couples cute moments made me keep watching the show but at some point they also become cringe.
Nothing surprised me about the story and it was predictable. So I would say Lovely runner is just overrated.
