The Heartbeat of Prison

College student Lin Yimo accidentally got lost after having fun in the dormitory and was abducted by a group of mysterious people. She met a silent and cold boy who always protected her inadvertently - she secretly called him "One". In the wasteland where they were imprisoned, fear and inexplicable heartbeats intertwined. She asked her directly about her feelings, but he evaded in a panic and made duplicity. Their feelings quietly grew in their vigilance. Until her classmate Lin Xiao risked her life to come to the rescue, she resolutely chose to stand by "One"'s side, and this bond that transcended identities also hid secrets related to her family.
