Comment by hyaci on The Precious Sister Of The Villainous Grand Duke - Chapter 78

if u dont want them to fall in love, just stop reading now. bc from here there's only a high hill. 
they never considered each others brothers. at the start, she only wanted to not get killed and save her life, while he was the one who actually hated her and wanted to MURDER HER FOR A LONG TIME. but they started to get affectionate to each other, but neither of them mentioned that they saw the other one as a sibling, as they both alway knew they werent blood related. they just grew fond of each other without falling in love bc obv they were kids/minor. only now theyre starting to a little realize new emotions like jealosy bc she is becoming an adult too and more mature. 
pls if u saw them as siblings just drop this manhwa and know that u got it all wrong from the start
