Butterfly_Effect's Manga

This was cute not too much drama and the main couple was really cute but is this the censored version? I found the +18 version somewhere else but is not on the official platform so I'm confused. Anyway the only thing I didn't like was the second couple, I didn't like them together and instead of their chapters I wish I could've seen the main couple more specially because this manhwa is so short, also the author forgot about the other friends and I wanted to know if finally the grandma got out of the hospital
