Love Someone Who You Love or Love Someone Who Loves You

I choose love someone who you love. Because when we need some help, he/she would sincerely give his/her help for us and he/she would not expect any responses from us. Another reason is when we need any suggestion about anything, he/she would give his/her best opinion for us. Human is a social creature, and they automatically need friends to solve their problem or even share happiness, who would understand us beside the people whom we love, right?
