Enjoyable Story with Spicy chapters

I really like the male lead here, how he's trying to save someone's life and gets caught in all these protagonist like situations.
The sister character needs more chapters and development i feel, some family bonding time. Don't get me wrong the 2 main heroines so far are both unique, well written and amazing and I early await each chapter.
My other hope would be for the author to mention the other heroines mentioned early on
