我订婚的时候求你要来可是我不想砸你订婚宴
[wŏ dìng hūn de shí hòu qiú nĭ yào lái kĕ shì wŏ bù xiăng zá nĭ dìng hūn yàn]
Translated to 'When I was getting engaged, I begged you to come but didn't wish to ruin your own engagement ceremony'. It implies the speaker feels a complex and bittersweet mix of emotions—pleased that the beloved came for the special occasion yet distressed or conflicted over disturbing someone else’s similar moment of happiness.
