I had a headcanon where Shuichi was a girl idol when he was like 8-10(?) Now i cant get it out of my head. It is stuck-
Idk what to name it so i guess ill call it LIAU (Lil' Idol AU) for now. This is a non despair au keep that in mind. The pairing here is mainly oumasai. But it is fine if you wanna use this headcanon for your pairing.
One day his mother (actress) wanted to try making him an celebrity. So she and her husband tried to audition him as one. But he had a sort of stage fright at the first audition and was not accepted. His mother was quite stubborn about her idea and wanted him to experience the life on tv (She actually would stop if Shuichi said no but he just wanted her to be happy so he just follow what she wants [she is not a dickhead don't worry lmao]). She then got an idea of him cross-dressing as a girl, an idol. As usual he accepted, when he first put it on, he kind of liked it, wearing skirts and make ups (eyeliners are his favourites and was stuck with it even after he stopped dancing and such). He sees his idol persona as a mask. Because of this he felt confident in doing things he wanted because no one would know him (other than his family and manager). He auditioned on a tv show and it sort of worked out-
That tv show he audition on is called Little Stars that went on for 4 years. The shows is centered around 5 idol kids, the leader Lina, and the members Miya, Ryo, Aiko and Hina. His idol persona, Miya, was the most favourite among the audience. Things that made her famous are her shyness, being a mood or being relateable af, boldness at stating her opinion, the fact that she is a good singer and dancer, and her cuteness is what captivated the audience. With the show famous internationally the amount of fans she has was- a lot.
Because of this he was a celebrity at the time just like how his mother wants him to be and they went on tours to sing, dance and others. (He was also scouted by hopes peak but they didn't had a chance to invite him) He also appeared in other tv shows, movies, interviews, etc. Shuichi honestly didn't mind it although it stresses him out in some cases. Few things he learned when he was an idol was singing, dancing, violin, gymnastics, calligraphy, judo- (In my au he is a natural talent, he can learn things he is interested in at a fast rate but didn't have a courage to show it.)
Around the age of 10 his parents soon lost interest in him since they find other things more interesting, leaving him with his uncle. After noticing his parents aren't around anymore, he didn't feel the need to continue. So, he immediately stopped being an idol. The world was on fire when she suddenly disappeared although it died down after a couple of months where Miya posted a video apology saying she cant go on anymore because this was not the job she wanted to do for the rest of her life. Her fans respect her decision although there are some who objected to it. (they do be crying)
An so Shuichi abandoned his persona Miya and retired being an idol after 2 years. Although he felt he is going to miss it - he truly did and move on with his life living with his uncle. When he first sees his uncle job he felt pretty normal but as time goes on he became more and more fascinated by it. His uncle then invited him as his assistant where he accepted. And this and that happened shakaiwoajq, now he is the ultimate detective in 79th class.
Then this festival came up and the class decided to do a musical show - Kaede was the one that suggested it lol. Then it all went downhill-
Lol i might make part 2 since its kind off spoilers if i did it (totally not because i dont know how it will go). Tho im sure miya will somehow make a appearance in the stage. Im just not sure how she got there baha.
This au is a branch or another version of my other au called Unknown Identities Au. I'll make a post about it in the future. You may drop some questions. Tho dont expect me to answer all of them ahah-
