A goat and a wolf take shelter in a hut on the night of a storm. They can't see each other in the darkness, and while talking, they find they have a lot in common and form a friendship. They make a promise to meet the next day in front of the hut for lunch, they will recognize each other with the phrase "One storm night". When they return the next day they are both surprised that they are a goat and wolf.

After Gabu and Mei meet secretly, Mei returns to the herd to discover that her little sister, Mii is running a high fever. But the herbal remedy to lower fever only grows up on a high rock near the wolves' territory. When Mei meets with Gabu to tell him about it, He tells her that it is too dangerous for her to go there. Gabu then lies to Mei, telling her that he has climbed that rock many times and can retrieve the plant with no problem.

Gabu is scolded by his boss, Giro for messing up during a hunt. When Gabu meets up with Mei, She asks him why he looks so worried, when Gabu explains the situation, Mei misunderstands and thinks that Gabu is the boss of the wolves.

Mei picked some berries for Gabu and her to eat together when they meet. When Gabu gives Mei his share of the berries, she realizes that he only likes meat, and jokingly accuses Gabu of meeting with her to eat her. Although goat meat is his favorite, he tries to convince Mei that he doesn't even like goat meat. Mei decides to reverse roles where she plays "Mei the Wolf" that stalks and attacks "Gabu the Goat".

Some swallows come flying by to sing about things they saw and heard. When a pair of the swallows see Mei and Gabu together, they start singing a song about a goat named Mei and a wolf named Gabu that are "secret friends". Worried that they might sing the song to the wolf pack or goat herd, thus exposing their secret, Mei and Gabu chase the birds all around trying to convince them not to sing that song.

Upon retuning from their meeting at Taka Taka Plateau, Gabu is confronted by some of the wolves from his pack about smelling a goat near there, and Mei is likewise confronted by some goats saying they smelled a wolf near there. Realizing that it is no longer a good place to meet, Gabu and Mei each set off to find the perfect place where they can meet without being discovered.

A goat named Kuro, who is the grandson of the black goat High Elder comes to visit the white goat herd one day. When Mei goes off to look for a four-leaf clover to give to Gabu, Kuro comes by to help her find one. Gabu happens to pass by and sees Mei with Kuro. Later when they meet, Mei sees Kuro on his way back home, and she runs over to say goodbye, Gabu Thinks that Mei would rather be with Kuro and tells her that they shouldn't see each other anymore because she would be happier with her own kind.

Gabu goes to the meeting place to wait for Mei, he is extremely hungry and tired because he has a toothache which has made it difficult to eat or sleep for the last several days. He goes into a bush to take a quick nap while waiting. The bush happens to be in the middle of the spot where the goat kids from three herds come for their annual field trip. Although he made a vow to Mei to never eat another goat again, all those tasty little goats running around may be too much for Gabu to handle.

Lolo, Giro's sister gave birth to baby wolves. The pack decides to throw a party near a field where Gabu told Mei to meet him so he could show her something spectacular that she might like. If mei goes back home, she will miss out on the surprise he wanted to show her so he has to keep her entertained just outside of the area until the party is over. So Gabu has to do a lot of running back and forth between the party and Mei.
