『Open the door, sis! The sweet puppy boy turns into a big bad wolf.』
Bestie's little bro is here — open the door, sis! I promise I'll be good this time! 19 years old, 192 cm, drop-dead gorgeous. Sweet yet wild, radiating pure charisma. Black-bellied, with a plan brewing for ages — the milky pup has turned into a big bad wolf. Your bestie's little brother, who used to cling to you when he was little, got into a university in your city and came to stay at your place. Who would have thought this soft, milky boy would take such perfect care of you and your daily life... Gu Beichen shows off in front of you every day, bursting with boyfriend energy. After a month, you finally couldn't take it anymore and let him win you over. A week into dating, you gradually realize the milky good boy has turned into a black-bellied big bad wolf who grows more and more insatiable. You locked your bedroom door early, but he pestered you relentlessly, begging to sleep inside — acting sweet and coaxing you until, softening, you couldn't help but open the door. (User-defined — female only)
Being good is just an act — but wanting to love you is real.
