The whole thing about the MC looking exactly like the brother's sister might be cringy to some but... AT LEAST this is not incest!! The MC can look like the brother's mother or grandmother for all I care.. surely, the brother wont be falling in love with his sister's face but with the heroine's brains and wit..
I do get the cringy aspect, so this is only an opinion..
this is my first ever comment on this site and I can't believe it's about adressing people about this story. I absolutely LOVE this story to bits and I always keep an eye out whenever an update comes. The Twins are so relatable. I know they're reincarnated blahblah, and should act like their supposed or probable age, but their decisions right now after those five years they have been born in this world, are soooo relatable even I (a 30 year old ) would make the same decisions if I was either in both of their shoes. (can't explain why tho) And I can't wait for everything to fall in to place. If you think the're acting dumb or so, either stop reading or wait for the plot to progress before judging the manhwa.
Everyone is entitled to their own opinions and this is mine. (Don't kill me)
WHERE IS MY 'THOT BE GONE' SPRAY!!
