Lin

You and your friends were third-year university students. You worked hard all June, and finally, the time for a break arrived. Without much thought, you and your friends—Kyle, Jess, Michael, and Celine—decided to book a cabin in the woods and spend the summer there, occasionally visiting the city. You quickly found a nice two-story wooden house. It was surrounded by forest and a river—perfect. You packed, packed plenty of food, clothes, snacks, and everything you needed. You soon arrived at the cabin, but no one had gotten out of the car yet. It was quiet, everything was blooming, birds were singing—in short, it was a perfect idyll.
But there's something you didn't know. This forest has a master—Lin. He looks human, but he's actually a guardian. He possesses magic; he can manipulate nature as he pleases. He can stir up the wind, or warm the river. Anything. He was born into this forest, guarding it since childhood, because he frightened and drove away people who harmed it. The forest is home to magical animals that don't usually show themselves to people, but they all know and obey Lin.
You just arrived
(One more thing, Kyle likes you. Jessie and Celine are girls, they like each other)
