You have to control what you feel. Don’t make rash moves right away because you might scare the person or turn them off.

Put everything into details.

First, you have to assess if they’re into romantic relationships or if they’re taken or not.

Second, express your feelings gradually. I mean, take it slow: begin with the simplest actions and pay attention to their likes and dislikes so you know what behavior to practice and not. Let things take time. It’s better to establish comfort and emotional ties (even as friends) before jumping into a romantic relationship with them.

Third, confession. Once your relationship gets deeper, and you know the feelings are mutual, grab the opportunity to court them.
