Reminds me of Miyagi x Shinobu from Junjou Romantica, i mean the gap of 18 years is a thing but them just being cousin and they COULD love eo as couple ya know, just not all peeps would go for their own cousins, though actually you COULD MARRY your OWN COUSIN, but that's not the point, I wanna say, this story is totally grapsed my interest as it's from same sensei i love reading for, also this is alt ver for some couple which i forgot seme's name but the uke is bootiful and tried to get revenge for seme because things happening in past, yea i wished to read the seme's friend story but couldn't find which or it doesn't exist yet, but yea i really enjoy reading this manga ahakss
