亲爱的房客

林健一（莫子仪 饰）是住在顶楼的房客，但他不只照顾年迈患病的房东周秀玉（陈淑芳 饰），还收养了她9岁的孙子王悠宇（白润音 饰），这一切看似超出普通房客的行为动机，在周秀玉去世后受到质疑，很多人怀疑他是为了顺理成章的获得遗产，他百口莫辩，因为这些举动背后隐藏着一段不被承认的感情，也更是他思念一个人的方式，而那个人正是房东已经过世的儿子…For the past five years, Lin has been looking after the son (Yo-yu) and the elderly mother (Mrs. Chou) of his deceased boyfriend (Li-wei). They live together like a family, and it is Lin's way of remembering Li-wei - by continuing to be in the life he once had and loving the people he once loved. But when Mrs. Chou passes away, her other son (Li-gang) returns from overseas and discovers that Mrs. Chou's property is passed on to Yo-yu, who has been legally adopted by Lin. Li-gang contacts the police, accusing Lin of killing his mother for attempting to own the property. As the ensuing investigation continues, more and more evidence mounts against Lin.
