Lava, Wave, Tum, and Kratae work together to fix a small eatery
Nurse Kratae checks on Wave, who explains that while his brain still remembers how to do things, his personal memories remain missing. Kratae assures him that recovery takes time and reminds him of Dr. Wut’s advice to go out and experience things that might trigger familiar senses like sight, taste, smell, and sound. She then asks Lava to take Wave out more often.
Meanwhile, Lava, an architecture student, decides to help renovate the small eatery where he and Wave once ate. He starts designing the layout and, together with Kratae and Tum, helps the owner repair and restore the eatery.
As the renovation nears completion, the owner’s son suddenly shows up demanding money. When his father refuses, saying he has none to give, the son becomes furious. The group steps in to defend the owner, but the son grows even angrier and forcefully takes the money before storming off.

Lava reveals he’s into men; Minor accident with Wave follows
After fixing the eatery, the group went to the beach to swim. While applying sunscreen, Wave mentioned that he thought Kratae might like Lava. Lava shrugged it off and said that he was just being friendly—then openly admitted he likes men, not women. Curious, he asked Wave if he remembered his own sexuality. Wave admitted he was unsure and needed time to figure it out. Then, Lava offered to help him find out, but Wave, uncomfortable with being touched, quickly stopped him.
Later, after having fun swimming, as they headed home, a pickup truck suddenly sped toward them and knocked them down. Lava suspected it was the eatery owner’s son seeking revenge, but Wave doubted it, saying their earlier encounter wasn’t serious enough. Lava, however, argued that even small grudges can lead to deadly consequences.
Then, a flashback revealed Lava’s past. Back in high school, after a motorcycle purposely hit a passing woman, Lava fought with the driver. The driver later tried to shoot him, but his father stepped in to protect him, losing his life in the process.

Back at home, Lava and Wave look for Uncle Peng and catch him and Wut coming out of a room, flirting and kissing. Later that night, the two talk about it in their room. Lava wonders why Peng hasn’t told him about the relationship, but Wave suggests they might just not be ready yet.
Moments later, the power goes out, and Wave gets scared. Feeling hot, Lava takes off his shirt while Wave hides under the comforter. As Lava moves closer, Wave tells him to move away, saying he feels uneasy. Lava teasingly asks, “Uneasy or turned on?” before saying, “I think I know now—whether you like women or men.”
Then, Lava runs his hands over Wave’s body, saying, “memories are triggered through senses and touch.” He guides Wave’s hand over his body, kisses him, and leaves after whispering, “So, you’re aware now.”
