In the end, I still end up reading this… I mean it’s such a waste of art!!! The art style is so beautiful that I can’t help but forced myself to read it.
FYI I skip the chapters, and coincidentally jumped straight to ML confessing to the FL. I think there’s a time skip? Cause the when the ML confess to the FL, she’s already a college girl. And I read it up to the latest chapter
Ughhh… I must say despite of every character in this story has a common sense and know the social standard, they still support and push the FL to pursue her feeling for her “sister’s ex-boyfriend” like wtf?!
Like I know FL is feeling guilty to her sister, because that is your sister’s ex. But, I couldn’t believe like honestly believe that the sister is alright with this!? She’s way too sweet!! You could’ve just scolded and get mad to them!!
It’s Siha Gu from Star Dream Idol Project!! You can read this in here https://www.mangago.me/read-manga/star_dream_idol_project/
It’s already completed so you can start reading it! And she’s the MC! It mostly focuses on Idols, Revenge and romance in a side line. But the overall story is 10/10. Sorry I just loved this manhua ლ(´ڡ`ლ)

Dang it! I'm planning to read this manga because of how pretty the cover is. I guess it's my fault for not reading the summary, but the art style looks so good. The ML and the FL's sister looks so good together that they treat FL like their practice child.
After finishing the 1st chapter that's when I realize the kid was the FL and the ML is the sister's bf. What a waste of art and a possible more cute interaction between ML and the sister.
It was a nice art style but I won't read it any further, I feel hurt for the sister T^T
