It was supposed to have a pleasant outing and date at the top of the mountain restaurant, but Nan (Honda Eye) and Nishino (Atsuki Maiko) were killed!?Someone sets a trap...And the life of Nishino, who was incompatible with Nan, saved by the fire and water...

One day when the commotion of the strange letter came to an end, Nan (Honda Eye) and others received an invitation letter from the mountaintop restaurant, which said that you can eat at the stunning couple's seat.Nishino (Makoto Toshiki) was a little hesitant about the positive climbing of Nan, but in the end he was deceived by Nan's sweet words, and the four of them went to the mountain together.Seeing Nan wearing regular mountaineering equipment, Nishino teased him. Even though he came to the mountain, the little conflict was still the same.The two bet on the right to have a meal with Kitako (played by Iwase Yoshi) at the stunning couple's banquet, and rushed to the top of the mountain.However, Nishino felt anxious about Nan walking briskly on the mountain road and sprained his foot on the way...

On the other hand, Dongzi (played by Shida Miku) and Beijun took a cable car to head towards the top of the mountain. When they reached the top of the mountain, the weather had completely deteriorated and thunder came from afar.Moreover, there is no restaurant you should find on the top of the mountain. The staff of the introductory office said that the mountaineering route written on the invitation letter is by no means for beginners.Dongzi was angry at someone's malicious harassment.It started raining soon, and Nan took Xiye, whose foot was injured, to take refuge in the cave and found that Xiye had a fever.In his vague consciousness, Xiye, who was sleeping under Nan's encouragement, suddenly woke up after a while and found Nan who was sleeping beside him...

Then, taking the event in the cave as an opportunity, Nishino became only considering Nan's affairs when he noticed, and was confused about the change in his mood.The contact between high school classmate model Aoyama Masahiro (played by Suzuki Yuka) is also continuing...The truth love that makes Nishino's student life dark is also obvious.
