The man broke into the hospital, grabbed a knife and drove a nurse, and excitedly asked the hospital for painkillers. As a doctor, Ding Soo Hyun came forward to negotiate with the man, promised to give him medicine, and asked him to release the nurse.
Just as they were about to exchange, the nurse suddenly struggled violently, the man desperately grabbed the medicine and fell to the ground accidentally, the blade in his hand slashed Ding Soo-hyun's neck.
The security guard on the side immediately subdued the man. And Ding Soo-hyun was lying on the ground, clutching his neck in pain, blood gurgled from the wound and flowed all over the ground.
In the aquarium, Kelu quietly observed the animals swimming in the water, and the trees were also swimming in it. When she looked out, she had hallucinations, thinking that Cao Shangjiu was going to be bad for Ke Lu, and was so anxious that Ke Lu pretended to be a red stingray outside, which made her laugh again.
The two return to the tree's shop together and see their patrolman friend Park Joon-young chatting with the tree's mother. Tree's mother's words were full of love for Jun Purong, but she had a different attitude towards Kelu, disliking her daughter and taking care of him like a mother. The trees went away in a hurry. Kelu explained that he usually does all the housework at home, and the trees just stay there and then go home.
Just after returning home, the trio received another urgent entrustment case, so they immediately set off to the scene. The deceased was the doctor Jung Soo Hyun. While sorting out the relics, Ke Lu found a letter written by Dr. Ding to his beloved, so he showed it to Dr. Ding's parents and asked them if they knew this person. As a result, Dr. Ding's father saw the letter and threw it directly into the fire in front of him.
Ke Lu was taken aback and hurriedly reached out to the fire. It was too late and all that was left was a pile of burnt confetti. And he still collected the scraps of paper.
After some discussion, the trio decided to find Dr. Ding's lover. Among the relics they found slip-stops (the stuff that holds the cello in place) and a concert ticket. There are four cellists on the flyer, three women and one man. Everyone had different opinions, so they decided to go to the concert scene and find Dr. Ding's lover.
Before the concert began, the three came backstage. Shushu and Cao Shangjiu asked the three female cellists all over, but found nothing. At this time, Crewe came over and told them that Dr. Ding's lover was the male cellist, Park Liyan. It turned out that when Ke Lu went to the bathroom, he found that the person next to him had "Soo Hyun" tattooed on his wrist.
They acted immediately, but Ke Lu walked over and asked Park Liyan if he knew Ding Soo Hyun. Park Liyan told Kelu with an unnatural expression that they were strangers now. Ke Lu just told him about Ding Suxian's death, and was pulled away by Shu Shu and Cao Shangjiu.
After hearing about it, Park Liyan hurriedly called Ding Soo-hyun, but no one answered. He called the hospital again, and the answer from the other side made him finally accept the truth in disbelief.
The trio were discussing whether to stay and watch the concert, but Ke Lu said that he planned to hand over the relics to Park Liyan after the concert. Just as they were talking, the three heard someone shouting out in front of them, and Li Yan disappeared!
Hearing this news, Kelu was even more determined that Park Liyan was Ding Suxian's lover, and the three decided to find him immediately. The tree guessed that he would go to the place where they first met, which gave Kelu an idea, and the three rushed to the hospital immediately.
Park Liyan, who came to the hospital, touched the scene and recalled the scene when they first met. It was Christmas a year ago, and Dr. Ding was on duty. At that time, Park Liyan was just an emotionally injured patient. Thanks to Dr. Ding's comfort, he gradually calmed down.
After the treatment was completed, Ding Soo Hyun, who was in the ward, came to Park Liyan's ward and saw that he was practicing the violin, so he went over to ask about his condition. Park Lee Yeon played a piece for Jung Soo Hyun. At the end of the song, Dr. Ding lost his mind because he was too engaged. He didn't applaud slowly until the applause of the audience behind him who was attracted by the song brought him back to reality. There was light in their eyes, and they looked at each other, bursting out of love in an instant.
The next development is like every couple in love, shopping, holding hands, watching movies, feeding things, whispering in each other's ears...
When he returned to his room to rest, Park Liyan received an admission letter from a foreign university with an address in San Francisco. Ding Soo Hyun immediately began to imagine the plan to take leave, which made Park Liyan very happy, and they began to imagine the plan in San Francisco.
However, on the day they agreed, Park Liyan was waiting at the airport for Ding Soo-hyun, who broke the appointment. Under pressure from his parents, Ding Soo Hyun could only choose to get married in China. Park Liyan quarreled with him angrily, and then the two parted ways.
Pu Liyan, who fled, walked slowly to the rooftop of the hospital. He was sorry for his words, but now he can't change the facts. The trio came over quickly, and Ke Lu told him that Dr. Ding left him a letter, but it was burned by Dr. Ding's father. They handed the confetti and other relics of the letter to Park Liyan, and then Kelu memorized the letter word by word. Park Liyan cried silently when he saw the two prepared rings in Ding Soo Hyun's belongings.
At the concert, it was Park Liyan's turn to perform. Before the performance, he slowly expressed his gratitude and nostalgia for his lover on the stage, and Dr. Ding's mother shed tears with relief. In the melodious tune of the cello, the two rings danced quietly with Park Liyan's fingers.
The jigsaw work depicting the coral island was finally completed by Kelu. However, he told his uncle that he could not understand why Dr. Ding's parents did not let them fall in love. He envied Park Liyan because he knew the person he loved. What he wanted to say to him, but he couldn't hear what his father wanted to say to him.
In the middle of the night, Cao Shangjiu, who couldn't sleep, remembered once again how he injured Xiu Che, so he got up and went out to Zicheng Sanatorium. He stood absentmindedly beside Xiu Che's bed, although he knew in his heart that he would not be able to get up, he still shouted to wake him up quickly.
