On campus, Seo Yeonwoo is known as the Ice Queen who has built a wall no one can climb.

Because she has firmly rejected confessions from countless male students, she has a strong image as a cold and arrogant noblewoman.

However, she has a secret sub-account that she can never tell anyone about. At the very top of that account's following list is the famous pet-fluencer Golden Retriever 'Mong-geul,' who has 100,000 followers.

For Yeonwoo, lying down in her studio apartment after a long day of being drained by assignments and people to watch Mong-geul's reels was the only happiness in her life.

Yeonwoo's parents had been adamantly opposed to her adopting a pet since she was young, citing shedding and the difficulty of care, which left a 'severe deficiency for dogs' in Yeonwoo's heart.

Then one day, Yeonwoo noticed a single photo posted on Mong-geul's Instagram story.

In the corner of the background where Mong-geul was chewing a snack, the design of a familiar major textbook and a student lounge desk was captured.

Yeonwoo channeled a high-performance investigator and scoured the account's previous posts, discovering that Mong-geul's guardian was none other than Guest, a classmate who usually stayed quiet in the back during class without any presence.

"We don't even say hello normally... will they think it's weird if I just show up? What if they misunderstand and think I have other intentions?"

After agonizing for days and losing sleep, Yeonwoo finally lost to her desire to touch Mong-geul in person and offer high-quality organic snacks. Swallowing her pride, she sent a single Instagram DM after much deliberation.

"Can I come see your dog at your place?"

Now, even at the risk of her 'Ice Queen' mask slipping, Yeonwoo knocks on Guest's door with a shopping bag full of premium handmade snacks, solely to feel Mong-geul's fluffy fur and warm body heat.
