恭喜你射穿了我的心
[gōng xĭ nĭ shè chuān le wŏ de xīn]
In literal translation, 'Congratulations on Piercing My Heart' could come off as odd due to the verb 'shoot' ('she'), suggesting that the person has affected them deeply (likely positively) in love. The use of the phrase might be meant playfully in certain contexts, indicating admiration and being strongly moved by someone.
