It's a merman, not a piranha

As a matter of course, the professor did not agree to Ruisi's marriage proposal. He firmly believed that they could wait until the day when Ruisi became an adult. Compared with the professor's firmness, Ruisi was not so confident. It stopped for a while, but the visits became more frequent. At first, the professor had to refuse it with righteous words, but later, under Reese's soft and hard paving, he half pushed and gave up. Even if he didn't show it, it was still very rewarding to see that the person he liked was so dependent on him.

Let’s say that the conversation between the professor and the mermaid Ruisi was very smooth that day. The two took what they needed and cooperated happily. The mermaid Ruisi wanted an unrestricted body, and the professor wanted Ruisi to live well. Reese will return to her body, and the mermaid will return to the sea, so the two who have no witnesses of the Fidelity Curse sign a contract.

When a mermaid gives a kiss of true love to a person, it is one-sided, and the soul of the recipient responds at this time, which will result in sharing between both parties. As a wizard, as long as you respond with magic power when accepting a kiss from a mermaid, it will trigger a two-way sharing. , This sounds easy to say, but it is very difficult to operate in practice. Using magic power to respond to a high-power spell without the help of a wand, even Snape is unlikely to succeed. Snape temporarily researched the potion on hand Set aside to practice responding to high frequency magic.

The mermaid Ruisi signed a contract with the professor. Dumbledore was worried about the remnant souls outside. I went to look for the acrylic in the Forbidden Forest. I learned the method of exercising the soul from the clan, and I gave it to Reese to let her use it for practice.

Everyone got busy, but seemed to calm down again. Everyone was making their own preparations, making Reese feel that as long as she survived this period of time, everything would develop in a better direction.

Outside the window of Slytherin's dormitory is the Black Lake in the silent night. Reese is sleeping soundly in the special huge fish tank. The tense Reese opened her eyes in an instant, and her blue eyes vigilantly searched up, down, left, and right in the room. With a bang, the glass separating the Black Lake from the dormitory exploded, and the water from the Black Lake gushed in. Si watched helplessly as the lake came rushing towards her, and she didn't have time to take any measures.

"Not good!" Dumbledore, who was still asleep, felt the change in the Slytherin dormitory. One of the protective magic circles there was broken. Dumbledore quickly went from the fireplace to the potions professor's office to inform Snape. .

Snape hurried to the lounge, and Dumbledore called for help.

In the end, the matter was safe and sound. The only unknown thing was the trace of Reese. She disappeared from the dormitory. Snape was sure that she went back to the dormitory. Damn it, he saw her enter the lounge before leaving. How could there be no sign of Reese in the house.

"Damn it! Damn it! They went back, but I still have to possess this weak underwater magical creature." A dark and sinister figure cursed something in the depths of the Black Lake.

"It seems that they have gone back to their hometown." After talking with the mermaids who overheard some words, Dumbledore said inscrutably.

"..." Hearing what Dumbledore said, Snape felt as if his strength had been drained at this moment, he turned around and left with his robes swung. He thought he could protect his beloved this time, but it seemed that he was too naive. He returned to the office and leaned against the door weakly, covering his face in pain. He fumbled to open the door hidden in the The phonograph locket in the clothes, looking at the focused and enthusiastic look of the villain inside, he was silent without making any sound, the warm liquid left a little water stain on his collar.
