穿着丧服参加你的婚礼好吗
[chuān zhe sāng fú cān jiā nĭ de hūn lĭ hăo ma]
The literal translation is 'Would it be okay for me to wear mourning clothes to your wedding?' It portrays one's inner struggle and unwillingness, having to attend the beloved's matrimony where the person is not a partner but a third-party spectator. There's an evident pain conveyed by choosing to metaphorically symbolize it with wearing somber funeral attire to such joyful yet personal event.
