Traveling Through the World of Beasts with My Best Friend, Both of Them Were Manipulated

[Best friend double wear × beast world × yandere × tsundere] During a trip to a deserted island, Bai Qingqing and Su Mian accidentally entered an imaginary continent ruled by orcs. — Suiling is a snake tribe boy picked up by Bai Qingqing. He is well-behaved and has excellent cooking skills. Every time he calls her "sister", her heart flutters. She thought he was innocent and harmless until she witnessed him swallow alive a gray rabbit orc who tried to get close to her. The snake's tail wrapped around her waist, and there was a paranoid possessiveness in the young man's eyes: "Sister, you said... You only like me." — Su Mian accidentally fell into the water while going out to sea and was rescued by a beautiful shark. The shark's name is Zhuo Lian, and he is the overlord of the sea. He feels that this little human is simply a troublemaker. Sometimes he thinks the sea water is too salty, and sometimes he says he is too cold. In short, he regrets saving her. However, this little human will share with him the delicacies on land, and also tell him some interesting things that he has never heard before. Although it is chirpy, it seems not bad. Until Su Mian kissed his scales, the little human didn't seem to realize that this was a marriage proposal ceremony to the shark. Zhuo Lian thought that it would be good to let everything take its course. But one day later, Su Mian stopped looking for him. Zhuo Lian lost his temper and went to look for her, only to find out that Su Mian was going to marry a wolf orc. He made a big fuss at the wedding, snatched Su Mian away, and held her in the sea for three days and nights.
