Step-by-step explanation:
The second stage of love is attraction, characterized by excessive attention given to a desired partner. During this stage, individuals may experience romantic feelings and puppy love, where they care more about the appearance and clothing of the person they are attracted to. This stage is influenced by social exchange theory, which explains how people weigh a potential partner's attractiveness against the likelihood of success.
