''Hey, old man.'' A young man said with a grin.

He was walking with his group of friends, and they had disheveled outfits, looking like usual delinquents.

They stopped in front of one shop, where an old man was sitting while reading a newspaper.

The old man turned his gaze towards the young man, ''What you want, brat?''

''So rude~ I am your grandson, yet you act like this.'' The young man looked hurt, but he was obviously acting.

The old man snorted, ''My memory must be fuzzy— I don't remember having a useless grandson like you.''

The young man's eyebrow twitched, ''Fine... You are old and all that... I don't blame you, and you might not remember, but I am your favorite grandson.''

''Is that so?'' The old man narrowed his eyes— he put the newspaper back on the table and stood up.

Even though he is around his 60s, his muscular figure couldn't be hidden under his shaggy clothing.
