Well, I think it is weird, when the timeline explains a bit more about the story that was originally just all about the old cliche rapist getting a pass because he's got a 'tragic past'. But, ah, well, guess that's just me....
There's plenty of comments with other readers who are as into the backstory, esp for the pink haired dude, so you have plenty of company. For me, everything in the backstory is by definition cliched...MCs with dead parents killed tragically and blah blah are everywhere.
I think I'm more interested in Blood Bank's flashbacks because that story is more well-developed, with better world building, and a more intriguing range of characters.
Honestly, I'm not all that into flashbacks unless it's used to highlight something in the character's personality or to display something important. However here it's just already restating what we already know. And while I do like the pink haired character, I don't see why we need a flashback about him that spans over several chapters
If you liked Blood Bank, you must read Moritat!! It's such a riveting read, with a set of intriguing characters and a plot that has the reader at the edge of their seat. Having had read all the Manhwas being released lately, my favorites were Moritat and Never Understand.
Is it weird that I enjoy the flashbacks in Blood Bank and get completely impatient with the ones in Royal Servant? This is interesting enough, I guess, but I'm dying to get back to the original timeline...
