I'm just gonna say it. I don't like Yutong's younger sister. I know she's portraying the typical fujoshi that fetishsizes BL, but dear lord, I find her annoying and kinda creepy. Why does she like imagining her older brother making out with his friend?! It would be weird if an older brother got turned on while imagining his younger sister getting railed by her boyfriend.
Other than that, I rlly like the story.
