Professor Dekapan invents a new potion that can revert someone's age, turning them back to their youth. Iyami somehow gets his hands on this concoction thinking he could get famous for his "youthful beauty". A mishap happens and it ends up in Chibita's oden. The now infected oden is coincidentally in some of the Matsuno brothers' dish, thus causing some of them to reverse their age.

Hey all you Osomatsu-san fans, welcome to my one-shot book, where I'll be writing up some lovely stories about these losers! I had taken a three-year hiatus from this book, but now I have jumped back into this fandom once again, so hopefully, I can make you happy with some more stories! Also, please bear with me when it comes to updating I'm not the best at sticking to a steady schedule, you know school and all that and also I apologize for any extreme out of character-ness, I'll try my best to nail down their characters! But, I hope you enjoy this book, anyway. (Check out that snazzy new cover) This is a female reader and lemon free story. Thanks for choosing to read my book!~ - Bed-Head Otaku

Osomatsu goes to the horse track but never returns, later, a note is found at the sextuplets' door that will never be forgotten.

☓ 𝐃𝐈𝐒𝐂𝐎𝐍𝐓𝐈𝐍𝐔𝐄𝐃 ☓ You were very much a wallflower during high school and are pretty much the same now, even in your twenties. The sextuplets never really noticed you in high school but you noticed them and were in silent envy of them being siblings as you're an only child and have always desired a brother or sister. Anywho, you now live in a penthouse and work two jobs: a cook in a cafe and a photographer. Everything is normal when you suddenly find yourself being a rental girlfriend, what happens when you end up being a rental for the sextuplets? Do you finally evolve from being a wallflower when the sextuplets call you ugly? And will you be the one to open their eyes on love? ⏤ᴅɪsᴄᴏɴᴛɪɴᴜᴇᴅ RANKINGS: 21.03.19 ⇢ #1 in RENTAL ⌙ Thank you so so much, my lovely Dollies! I'll continue doing my best for you!

For trash like me who are in love with Jyushimatsu. Requests welcome. *Art not mine* Cover Art by: http://aubreylimart.tumblr.com/

Did you fall in love with a certain Matsuno brother? Was it the cocky Osomatsu? The painful but precious Karamatsu? How about the nerdy Choromatsu? Are you into the silent misunderstood Ichimatsu? Maybe the hyperactive Jyushimatsu is your style? Or perhaps the two-faced Todomatsu is more up your alley? Hell, you might like a non-main character! Whoever it is, prepare for your daily dose of fluff~
