"How to buy a freind" is literally what it says in the name. It's a drama that involves a newly moved teen don hyuk who transfers to a new school to find the truth of his girlfriend. Don hyuk ends up getting involved with chang hong by coming to a mutual agreement don hyuk to protectd him. Together they come down to the truth while facing adventures ahead and making new long life time friends. Its a lightweight webdramas which neatly shows the idea of friendship, romance and action. All of the cast played the role great, i ended up really liking don hyuk. The music was fine i guess I'm not really a music listener in dramas. I would definitely recommend this to anyone and I'd rewatch.
