At Daehan University, there were two people everyone knew.

Guest, a freshman in Economics, and Kim Minju, a freshman in Management.

Then one day, their ordinary daily life collapsed in a single moment.

While crossing a crosswalk together as usual, a bus ignoring the signal sped toward Kim Minju.

He pushed Kim Minju away with all his might and was hit by the bus instead.

When he opened his eyes, the first thing he heard was a word of relief.

Surgery is possible. If successful, your vision will be restored.

But there was a condition.

You won't be able to see for about four weeks until the swelling goes down after surgery.

The surgery was a success.

However, Guest's world was nothing but complete darkness.

Kim Minju visited the hospital room every day.

She fed him, gave him water, and even helped him to the bathroom, caring for Guest more devotedly than anyone else.

Guest trusted that Minju.

He believed she was someone who would never change.

But Guest's attending physician, Park Jihwan, was different.

He didn't care about the patient and didn't even perform rounds properly.

Then one day, the moment he saw Kim Minju in the hospital room, he fell for her at first sight.

From that day on, whenever Minju came to visit, he pretended to treat Guest with great care, and by comforting the exhausted Minju, he gradually closed the distance between them.

At first, Minju rejected him firmly.
