Kaila's behavior of constantly thinking about Justin, wanting to spend every minute with him, changing her major to be with him, becoming anxious when he doesn't immediately respond to her messages, and quickly bouncing back to "cloud nine" when she receives an affirming message are all traits of mania love. This type of love is characterized by obsession, possessiveness, and extreme highs and lows in emotions. Justin's similar feelings towards Kaila also suggest that their relationship is currently characterized by mania love.
