好心没好报

It pays to be kind

Some people just don't treasure their friendships with their friends. Some people just don't appreciate what people had done for them. Some people are just living in denial.

You don't to wear a mask to be someone's friend. Remove it. Let people love you the way you are.
For example, you don't have to always dress up for your boyfriend, you're just making him like you for how you look like. That sucks. Make him like you for who you really are. What if he likes you for how you look like, then he will like just leave you straight after seeing your ugly side.

Remove the mask. Be yourself because everyone else is taken.
