Making a guess entirely on the phrase you put in the credits page. It could quite possibly mean "We'll take off our clothes and have funny time together."Alright, the part on the last page I couldn't translate...
I checked a Korean scanlation that just came out and it says something like, "Gotta put some meat on your bones." (Literally, it says, "You need to graduate from being an anchovy" in Korean, which is an idiomatic expression and obviously not a direct translation from Japanese) I usually trust Korean translation but I'll just keep it off since it's kinda redundant and not really needed.
