actually he could have debuted earlier if his parents signed in his place, i mean just looking at sexy zone marius yo debuted as an idol at age 11, matsushima sou at 12 and satou shori at 13, so him having been younger at the time of his debut wouldn't be too far fetched
plus looking at how he wants to have a tv debut at age 30 sounds pretty late for it, most models get into acting at around age 20-25 but who rlly knows i mean do they usually sign kids for 20s fashion mags, maybe he just looked rlly mature as a kid who knows

actually it could also be a typo bcs i looked for raws the one i found is not very clear but i am pretty sure it says 1 not 15 but who knows the kanjis arent clear enough to read
and looking at the first two chapters 15 years sounds pretty far fetched considering that he still didnt make a tv debut after 15 years of career (usually it doesnt even take 5, if you r popular enough you could even make it in 1 year) , also strange he doesnt really know about his editor's phobia after 15 years of working with him and honestly models have a rlly short lived career i find it very unrealistic to believe a magazine model is being used for 15 years, especially a reader's model, thats why you see plenty of model-turned-actors around, most suck at acting but they are still in demand due to the fanbase they built during their modeling career
He was scouted 15 years ago (chap 1 page 10)
So he's actually more than 30 years old (let's just say the legal age to sign something is what? 16 or 18?)
He doesn't look it.
