The Lovely Demon

Ms. Lovely Demon falling inlove with Mr. Nice-Guy
Mr. Childish Drummer falling in love to Ms. Lovely Demon
Ms. Goody-Two-Shoes who would do anything for Mr. Nice Guy
And the Mr. Nice Guy who can't move on

What would be the love story between these 4?

A stoy of love, betrayal, hate, regret and forgiveness

you can never betray him/her without breaking your heart first"
