我的心被你上了锁却忘了把钥匙给我
[wŏ de xīn bèi nĭ shàng le suŏ què wàng le bă yào chí jĭ wŏ]
Translating to 'My heart was locked by you but you forgot to give me the key', this username portrays a situation where one person's affection is metaphorically 'locked' and they cannot access it themselves, as the loved one has forgotten or not willing to 'return' the 'key' for access, indicating a complex or unresolved feeling of love.
