说好不贪不想等我回来说好不念不伤等你回来
[shuō hăo bù tān bù xiăng dĕng wŏ huí lái shuō hăo bù niàn bù shāng dĕng nĭ huí lái]
This conveys a complex but resigned emotion, meaning that despite agreeing not to miss each other and not to hurt while waiting, one still deeply cares for the person who is absent. It's like promising to not long or be affected, yet being true emotions always break such promise, reflecting the complexity of human feelings.
