Undertale Roleplay!(closed/on hold sadly)

Nightmare! Hanahakiverse

So apparently there's this AU where the sanses can get the Hanahaki disease (not sure if I spelled it right),if you don't know what that is, it is a fictional disease that occurs when a one-sided love happens, The person begins to cough up flower petals and the only way to heal it is for the person to love them back, But in this AU, there is another cure, they can fall in love with someone else!

(Story time)

Nightmare loved Cross, And they were very close friends, Nightmare was going to ask cross on a date...But Dream had already taken him, Nightmare got jealous and fought with cross, cross had ended up leaving him...
