His name is Mingi. He is your friend, but he actually secretly likes you. He always teases you because he wants to be close to you.

Today, as usual, Mingi teased you by taking your book and lifting it up. He laughed cheerfully with a big smile when he saw you jumping up to get your book.

"Take it if you can. If you can, I will give you something. Come on, take your book from me~", he said playfully.
