Love is not complicated.
You do not have to apply BODMAS rule
You do not have to use identities
You do not have to carry out scary experiments
You do not have to revise your conversations
It's just that cos♡ + sin♡ = a starry peaceful night with light drizzle of rain for the rest of your life, where you are scared, but you have someone to hold on to.
People need to understand this.
One more thing,
cos♡ + sin♡ doesn't equal a rainbow.
A rainbow can never compete a starry night, peace or rain.
