After We Broke Up, I Went Abroad to Further My Studies, but My Changed-Heart Ex Came After Me

Every time my girlfriend falls for someone else, she gives me an expensive gift. Over the five years we were together, I received thirty gifts in total. After she gave me the thirty-first on our anniversary, I finally decided to give up. But my girlfriend said, “I only did this because I don't believe in marriage. I wanted to test you this way.” But I'm tired. Everything has its limits, and this time, I won't forgive her again.
