Ichimatsu Matsuno has been hiding many secrets from his brothers. Of course, as all secrets do, they eventually come out. See how it affects all of the sextuplets in the Matsuno family. (I'm really bad at descriptions haha sorry. There's not alot of Osomatsu-San fanfiction on here that's not the sextuplets x reader so I decided to write this! Hope you guys like it.)
