With the fall leaves rustling outside her apartment, Tae is alone, she always has been, or at least that's what she has thought for a very long time. Even though she has friends, even though she is grateful for them, she can't trust them with everything, that's too much of a gamble she's not willing to take. One day her emotional state seems to tip over and she's running from all she's known. Is it because her heart trembles? Her heart trembles from loving someone forbiddenly? Everything blurs for this girl, who yearns to be herself and to be accepted by society.
