Can you please give me a title to describe the outline of this romance novel?

The male protagonist, Gong Yize, fell in love with Fu Siyu, a quiet and elegant woman in the same grade and different classes. Fu Siyu did not agree, and Gong Yize was forced by his father to go to France to study at university. Before he left, he gave Fu Siyu a four-leaf clover and told him that he would definitely find him, even if they couldn't be boyfriend and girlfriend. In his junior year…As expected, Gong Yize found Fu Siyu's school, but he didn't have anything to do with Fu Siyu. At this time, he had a girlfriend, and Fu Siyu fell in love with Gong Yize and his current girlfriend, Liu Jiexu. In the twists and turns, not only did Fu Siyu fail to break them up, but it also made their relationship better and better. Later, he finally gave up. On Valentine's Day (also when he and Gong Yize were about to get married), he found that he had completely lost to Liu Jiexu. She gave Liu Jiexu to Gong Yize as a gift on Valentine's Day. Lovers get together... [Fu Siyu had a heart attack and had a relapse once during her argument with Liu Jiexu...] On the day of Gong Yize and Liu Jiexu's wedding, he didn't go. He made the four-leaf clover into a pendant and hung it around his neck so that he could be closer to his heart. A little more… It's best to use the four-leaf clover as the theme of the topic and name it
