Sean's collection of shoes amazed people.

Yesterday, Sean posted on his Twitter, "I'll accept 10 questions," starting a conversation with his fans.

Fans asked, "What are you thinking about right now?", "How can I spend my day happily if I'm feeling a little depressed because of the rain?", "How can I not fight with my boyfriend?", "When do you feel 'happy'?" and many others.

To these questions, he replied "Hye Young", "When it's raining, drink a cup of tea, read a book, or write a letter", "Treat him like a prince and look at his good qualities and compliment him, loving him as if today is your last day with him" and "All the time, as now is a present."

One fan asked, "Do you have more shoes than Se7en?" and Sean revealed a picture of his collection of shoes, catching much attention. In the picture, Sean had shoes of various colors and types, in an unbelievable amount.

Internet users who saw this commented, "Sean must have an obsession with shoes", "I think he could wear one per year" and "I bet he doesn't remember which ones he owns."
