From the perspective of the heroine, what does it feel like to have unrequited love with the people around you? What about confusion and pain? Is there someone in your heart that you can't touch but want to treasure? She does. That's how it was in college, they thought this was love, they thought they would always be together. But after all, this is just what they think. Dreams will wake up and time will change. After all, it's you or me who has changed, or we haven't changed at all. Everyone is so humble and weak in love, but yet unexpectedly strong.
