I use songs to inspire me when I'm writing stories, but I'm stuck on finding a good song in this genre. Help anyone?? Thanks :)

Hashimoto Yukari - "Lost My Pieces"
Quite a strong one IMO. It is an instrumental but strucks deep.

Forbidden love? Try Alluring Secret~Black Vow. It's a catchy song, but it's kinda...weird

OH MY GURD!!! I WUV ALLURING SECRET~BLACK VOW!! If by wierd you mean it has some Yuri/Miku x Rin/ Miku x Len/ Kaito - Miku, then yeah.

ALSO! Another good Vocaloid Sad/Forbbiden Love Song(s) is 'Sevant Of Evil' by Len Kagamine (Squel to Daughter Of Evil), 'Regret message' by Rin Kagamine (sequel to 'Servant Of Evil') & 'Rebirthday' by Len Kagamine (Sequel to Both)

>>4 Yay! I'm happy you like my suggestion. It's just awkward when you have the video open and your mom walks in at a bad time. :)

I have some sad Korean songs you can look up to;
Someday - VIXX
Gone - Jin
Madly in Love - Soyu ft Mad Clown
Without You - Hyorin ft Mad Clown
Rain Sound - B.A.P

Hope I'm helping you^^

Gackt - P.S I love you
Gackt - Sakura Chiru
Gackt - Flower
Gackt - White Lovers

All of them have great clips and sound ;)

"the wolf that fell in love with little red riding hood" by kagamine rin and len. it has more of a bittersweet sound, but the lyrics are pretty sad.
