Help caleb's limited card title is shown on the website, "触痛讯号" which means "painful signal" omg i cant do this 🥲

Based on the meaning, "触痛" can mean activating or touching on an existing pain (memory), so the story maybe about caleb's evocative of an emotional response that might have been buried oh god 😭😭😭😭 pls dont give me emotional roller coaster pg
