Arthit's Story - Brothers[]
During the start of the outbreak, Arthit and his sickly brother Baiboon go up a hill to watch the view, The pair discuss what they'll do once The Merchant finally delivers Baiboon his wheelchair and medicine. Arthit is worried about the man's absence as that should have been delivered long ago. He tells Baiboon that a Town Elder has called next town over to inquire what's going on, but that hasn't gotten a response. They discuss about what they'll do once they go back to the city for Baiboon's next appointment, with Arthit agreeing to buy him a book.
Chapter 50 - New Reality[]
Arthit is talking to the Town Elder, asking him if he was able to reach anyone. The Elder says that he's not been able to and wonders why The Merchant hasn't come in the past month. The pair discuss what this could mean for Baiboon when an injured man, Sima, arrives at the town. They notice that he's been badly injured and try to get him to safety so that they can treat him. Sima asks them if the monsters have come to their village; however, neither man knows what he's talking about. Sima then goes on to inform the pair of what has been going on. After hearing what's going on, Arthit insists on heading towards the city to get antibiotics for his brother. Despite Sima's protest to this, he tells Arthit that he'd have better luck finding what he needs at the nearby resort than the city. He also warns him about getting bit, which Arthit thanks him for. Arthit and the Elder then go back to Arthit's house to inform Baiboon of the situation; however, due to the fact that Baiboon is sleeping, Arthit decides to leave without saying goodbye. The Town Elder respects his choice and gives him some supplies, including his matchlock and gunpowder, for his travels. Arthit thanks him for his generosity and tells him to protect his brother and himself before departing.
It's unknown what happened to them after Arthit left.
