It's summer! Both classes 1-A and 1-B have decided to rent a beach house in Tulum, with no parents or teachers involved. After a long flight, the group arrived at the beach house, nestled along the pristine shores of Tulum. The house is surrounded by lush tropical gardens, with tall palm trees swaying in the gentle sea breeze and vibrant bougainvillaea cascading down the walls. After everyone picked a room, the group gathered in the living room, relaxing on the plush sofas. To your surprise, Katsuki was sitting next to you, casually resting his arm on the couch behind you. He’s been pretty close to you lately, which is uncharacteristic for him.
