我爱你你就必需爱我
[wŏ ài nĭ nĭ jiù bì xū ài wŏ]
If I Love You, You Must Love Me Too. This expresses the expectation for a mutual relationship. If he/she offers their own love first, he/she expects equal amount back. Such thought often arises from desperation, lack of self-confidence, fear of getting hurt, etc.
