是我自作多情是我心甘情愿
[shì wŏ zì zuò duō qíng shì wŏ xīn gān qíng yuàn]
'I Fell for You Hard on My Own.' This conveys a deep affection and a voluntary willingness towards feeling deeply for another despite knowing it might not be reciprocated. It can suggest both acceptance and self-acknowledgment about being the only initiator of these romantic emotions without expecting returns.
