Please choose the correct ending to complete the given sentence: Relationships: [header] How to make any girl want to kiss you [title] Understand the importance of the connection.

Chemistry is important because it is what makes romantic relationships different from friendships.

Ending1: Romantic partners will have common interests, hobbies, and wants. However, do not confuse chemistry for attraction. Ending2: If you are interested in a girl, you'll want to build some chemistry so that you can move towards getting that first kiss. [substeps] Don't worry if you don't immediately have chemistry. Ending3: [substeps] People develop attraction through interaction and familiarity. A friendship, as one should say, only exists based on familiarity and emotion. Ending4: Chemistry grows as a relationship develops and will seem always more powerful later down the road, when you commit to something. The chemistry should only be based on attraction.
