BNHA Soulmate AU where everything's the same except your chest glows when you look into your Soulmate’s eyes.

In this AU, love is a choice, subconscious or otherwise. When you love someone, you chose to put them before yourself, to a certain degree. Because of this, people can also chose not to love someone, and the soulmate bond becomes unrequited, on one end or both. Depending on the distance between the two people and the intensity of their feelings, the glow will be stronger or weaker. 
There are several types of love in this AU, and each type of love has it’s own color. These colors do not change from couple to couple. 

Pink - The color of childhood love in this AU. This is the purest types of love. However, this love is easily changed, influenced and forgotten.
