Watashitachi no Shiawase na Jikan

College instructor Yu-jeong feels unfulfilled by her career and falls into a deep depression, losing her belief in God. After she attempts suicide and survives, her actions strain her relationship with her devout Christian family, who regard suicide as a mortal sin. Seeking guidance from her aunt, Sister Monica, a nun who volunteers at a prison, Yu-jeong meets Yun-su, a death-row convict who also questions whether God exists. As the two become friends, they begin to recover hope and reconsider their rejection of faith.
