When he woke up the next day, Xingyu saw Miya sitting on the black mud flat building mud castles without fear of getting dirty, just like a little girl building sand castles on the beach. But the mud castle in Miyadui was much more delicate than the little girl. The mud castle can already be seen to be a section of the Great Wall, and there is an arrow tower in the middle. After Xingyu shook his head with a smile, he shouted, "It's time for breakfast." Let's finish breakfast! Mia intently printed the walkway on the city wall with her finger and replied, "It's almost ready." You eat first, I'll eat when I'm done. Xingyu thought to himself: "Wow! Sure enough, it's a crazy master. It's more addictive to play than I am. Xingyu had no choice but to go to the lifeboat by himself and take out the dried fish and water. Prepare to walk to Mia's side for breakfast. I thought to myself, "I don't know when she'll finish it, so it's a big deal to feed her." Thinking of this, Xingyu excitedly wanted to go to Miya's side. Suddenly, Xingyu remembered that the lifeboat that he once despised brought its own fire, and said to himself: "Stupid! There are coals of fire, but I didn't think of making a fire. ”

Xingyu took out the convenient stove, lighter stick, fire wool, fire clip and charcoal contained in the inner pocket of the lifeboat, and took them all to the shore. Miya wanted to look up to see what Heung-woo was doing, but as soon as she saw Heung-woo opening the convenient stove, she guessed what Heung-woo wanted to do. Mia let out an excited wah and ran over. Mia didn't use a lighter to make a fire, and looked at it curiously. Xingyu saw that Miya was interested, so he explained while lighting a fire: "First tear the fire wool and spread it on the ground." Then use the curette that comes with the lighter to gently scrape out some magnesium powder on the lighter and sprinkle it on the fire wool, don't scrape vigorously. Then put the lighter stick close to the firecracker, and then vigorously scrape the firestick, scrape the spark from the lighter stick against the firecracker, and ignite the magnesium powder on the spark. Ignited magnesium powder ignites flask wool. Then put the charcoal next to the wool and let the cotton burn the coal. Once the coals are burned, they can be clamped into the stove with a fire clip. Wait until the coals are red and the flames are extinguished, and then you can use it. ”

After the fire was lit, Mia put her hands on the stove to roast her hands, and the feeling she had not felt for a long time made Mia happy. Then Xingyu skewered the dried fish on the wooden sticks that had been shaved and roasted them on the stove. The two of them, who hadn't eaten hot food for a long time, were excited to eat while roasting, and the two of them were very happy. After eating, the two of them still gathered around the fire, enjoying the remaining heat of the stove.

Xingyu looked at Miya covered in black mud, and Xingyu said teasingly: "You! Covered in black mud, people who don't know think you just finished a black mud bath! As if discovering a new world, Mia shouted, "Black mud bath!" Roar! How did I not think of this. Mia excitedly pulled Xingyu and ran towards the mudflat. After running to the mudflat, Mia lies down and asks Heungwoo to help him pile mud on him. Xingyu looked at Miya, who was playful, and cooperated to pile the black mud on Miya. After Xingyu helped Miya to be covered in black mud, he half-lay on his side and listened to Mia. Mia closes her eyes due to the glare of the sun, and Heungwoo carefully admires Mia's face while talking to her. Seeing the beating little mouth open and close slightly, Xingyu couldn't help but lean down and kiss Miya. Xingyu is like tasting fresh fruit, and the more he kisses, the more excited he becomes. Mia found that Heung-woo's hand was in the mud, and his body felt like he was about to squeeze into the mud. Mia slapped the strange hand that had reached into the mud, and as she removed her lips, she exclaimed, "Don't be weird! The mud is almost gone! Xingyu had no choice but to help Miya re-pile the black mud with a bitter face. Mia saw Xingyu's bitter appearance, and raised the corners of her mouth happily as if she had succeeded in a child's prank. Seeing Miya's smug appearance, Xingyu couldn't help but lean over and kiss Miya fiercely. Then, in Mia's anger, he kissed Mia's forehead again before walking away.

Mia, who has been lying in the mud for a long time and is bored. Sitting up and looking back for Xingyu, he saw that Xingyu was sitting not far away looking at him. Miya took the initiative to run to Xingyu's side, quickly kissed him and ran away, and then ran into the sea with a smile, cleaning himself while swimming.

The day is spent in play. The two of them felt as if they were still on vacation at Mafu Island. It's just that the fine white sand has turned into a black mudflat...

In the middle of the night, Heungwoo always seemed to hear strange voices. The strange sound seemed to be absent. The feeling of uneasiness surrounds Heungwoo again.
