    Ichimatsu gets injured and is forced to walk home with Karamatsu. (No BL) (This might be a bit angsty.) Whoop and now another chapter with Choromatsu and Jyushimatsu getting into a bad situation at a concert. This is kinda just practice writing the characters. I might add several chapters simply writing from different perspectives. Warnings will be before each chapter.

    (Book 1 of 3) Ichimatsu has always been a loner, yet he secretly wants to change that. He lies to himself constantly, telling himself that he doesn't need other's help to survive... This story may trigger a few people. It mentions things such as: self harm, depression, anxiety, and suicide attempts. If you're NOT okay with those things, I would suggest you click off of this book right now. ~ Petunia Paisley If you cry easily like I do, maybe...have a box of tissues with you? I dunno. I cry while writing half this crap. You probably won't though.

    As Karamatsu reached his brother's school, he immediately saw his brother, playing with another child which seems quiet. And what caught his eyes was, the teacher. • • • This is a KaraTodo A/B/O fanfic made by me and Lys_thetrashcan! (check her out! she's really good at writing!) and this fic is based on my own AU which is inspired by @tjwjddl75's A/B/O family AU and Gakuen Babysitter! If you want to know more, please look at my IG, which is @samatsuno! Thank you for reading, and sorry for our missing grammars and things! • • • Note: They are not related here. Osomatsu and Choromatsu are Ichimatsu's parents. Karamatsu and Jyushimatsu are siblings. Todomatsu is Ichimatsu and Jyushimatsu's favorite teacher. Osomatsu, Choromatsu, Todomatsu, and Atsushi goes to the same High School (Osomatsu was the senior, Choromatsu was 2nd grade, Todomatsu and Atsushi were the juniors) Karamatsu, Osomatsu, and Atsushi are Alphas. Choromatsu and Todomatsu are Omegas. • • • The covers are made by me&Lys

    Being a cat idol was not the most original idea in the world, but [Reader] knew they sucked too much ass to care. Why should they? Someone who spent their days working at a cafe didn't deserve any form of praise. Or did they? (so uh, [Reader] goes by they/them cuz why not? This is my first fanfic I have the balls to post, so my bad if it sucks)

    (credit to the artist for osomatsu drawing) (PROBABLY REALLY SLOW UPDATES!!!) (might contain some mild language) (gender-neutral pronouns) (Y/N) has been having a rough week and needs a break. They decide to head to the bar to drink it all away. Surprisingly, they meet an unemployed man in a red hoodie alone and drunk. (Y/N) knew it would be nice to help him get home before he sleeps there but, what they didn't know was how that one red-hooded man would change their life. (A/N): This is my first fanfiction (and x reader) so I would greatly appreciate it if you point any mistakes or give any suggestions for future writings. I don't thing this will be the best since I'm more of a drawing person than a writer but I'll try my best!! Also, thank you to the person who helped me with the name if you're reading this!! i don't know your username so I can't mention you but, you know who you are!!
