My Green Plums Are Not Too Sweet

How can I say the three words "I love you" without any scruples? First of all, I need to know that if I say it, even if you don't agree, we can still be together as before. Secondly, I need to know that you have me in your heart, and you won't accept it just because you dote on me, because I don't want to force you. However, if there is a woman around you who has evil intentions towards you, I will definitely tell you, because your sweet little green plum will become sour because of jealousy.
