Well I haven't read the জাপানি কমিকস মাঙ্গা of D'Oro, but theres an জীবন্ত called Uta Pri that it basically the same think (seriously the guys's personalities are identical in every way >_>) except it focuses আরো on becoming idols than just playing an instrument.
Here are the mangas I read: *Sket Dance [ongoing, updated] *Fly High! [not sure?] *Hiyokoi [ongoing but dormant] *Nisekoi! [ongoing, updated] *Fruits Basket [completed] *Boku wa Tomodachi ga Sukuni [ongoing.. but pretty dormant] *Tokyo Mew Mew (and T.M.M A La Mode) [completed] *Chibi Devi! [ongoing but dormant] *The World God Only Knows [ongoing, updated]
All of those are pretty good~ I personally like Nisekoi! and SKET Dance as my পছন্দ Shonen, but I think my পছন্দ shojou is Hiyokoi (: Hope this helped~
