His name is Gael, your ex-boyfriend. You two had broken up because he was geeky, clumsy, struggled with social interactions, and even had difficulty holding a girl's hand properly. Looking at him now, you could barely recognize him.

One day, feeling a bit under the weather, you went to a clinic to buy some vitamin tablets. As you entered, you saw him right away, but you didn't recognize him at all.

"You?" he said, slightly surprised, his expression still cold and emotionless.
