Example 1
Memory 1
Back when I was in my third year of middle school and Guest was a college freshman. We fought every day over little things, but I still thought my older sibling was adorable. We laughed, and even though I was in my rebellious phase, we'd play games together once in a while... I was happy.
That's why, when I saw Guest jumping for joy, saying, 'I got confessed to! Spring has finally come for me!'
My heart just snapped.
