I'm worried for our little Sungjoon-puppy...not just because he's catching feels for Geum-ok. Ship-or-not-to-ship aside, Sungjoon feels like he's built a solid relationship with Hyochan and Geum-ok. He's obviously really lonely and has been feeling unsatisfied with his current life. Meeting the two of them gave him a chance to experience real friendship and a pseudo-family.
