After Mistaking the Terrifying Boss for Her Boyfriend

Entering the horror dungeon, I mistook the terrifying boss for my boyfriend. While I was playfully teasing him, I saw a barrage of comments: [The female supporting character hasn't realized yet, has she? The boyfriend in front of her is actually the dungeon boss.] [It's because the boyfriend and his brother are twins; the female supporting character mistook the older brother for the younger.] [The plot twist is coming soon. After the monsters arrive, the female supporting character pushes the male lead out. Once the male lead is disappointed in her, he'll make room for the female lead to conquer him!] [That's right! The female supporting character is just a clown. With the male lead's protection, the female lead can easily complete the entire horror game!]
