Marriage is like a besieged city. People outside the city stand on tiptoe to look out and turn the trivial romance of daily necessities into poems; while those inside the city are trapped in it, unable to discern the direction in the passing day after day. When the passion fades, what is exposed is not only the gap in the partners' living habits, but also the collision and tearing of values. Some people learn to be silent in the endless quarrels, crushing their expectations into drinking wine alone late at night; some people struggle to rebuild in the devastation, trying to salvage a glimmer of light from the broken daily life. Those unspoken grievances, unfulfilled promises, and the eternal questioning of "happy marriage" are all intertwined in this besieged city, trapping countless similar but different souls.
