No, i think its the other way around. Kill the lights (novel) was the first and at the end of the road is the second. ATEOTR first chp was uploaded in 2016 in kor lezhin, but kill the lights was uploaded in 2015 in novelupdates. So if someone was inspired by smth, i'd say it is ATEOTR author. But i have to admit, this manhwa adaptation is a mess compared to the novel. The novel is really good, i'd recommend it to you :)
Oh my I did read the comment wrong it probably meant End of the Road was inspired.
Anyway on baka it says it's from 2012 but on ridi it says 2017 SO WHATS THE TRUTH lol but it's by the same author who wrote Who's Your Daddy & One Step from Hell, this author really got a thing for toxic ML lol but those two stories are really good & the ML aren't as toxic as Noah, maybe since this was their first novel it's abit more messier, I won't be reading this but thank you for the feedback :)
Reminded me of “At the end of the road”
