Impure

A captivating beauty of an older woman x an obsessive puppy who seems calm and rational but is actually a scheming green tea

During the summer after high school graduation, Li Songqi looked after her best friend's younger brother for a month.

The boy was beautiful and delicate, quiet and sparing with words. He seemed polite and obedient, but was actually finicky and haughty.

Unable to resist her mean streak, Li Songqi often teased him until his eyes welled up with tears.

At university, she and her friend planned to watch a movie. Then she overheard the younger brother badmouthing her behind her back.

"Someone like her can actually get a boyfriend? Her boyfriend must have it rough."

She leaned against the door and lightly tapped the panel with her knuckles. A hint of amusement glimmered in her peach-blossom eyes as she drawled, "Little brother, you shouldn't talk about people behind their backs."

At the sound of her voice, he turned around, eyes wide with shock. His fair, handsome face instantly turned bright red.

Later, she got a second boyfriend, and the younger brother caught them kissing downstairs.

Embarrassed, she tried to change the subject, not wanting to corrupt a high school student. But the younger brother gave her boyfriend a critical once-over and asked in a sarcastic tone, as if on purpose, "Did you get plastic surgery, big brother? You look different from the last time I saw you."

In her second year at work, the younger brother got into a university in the same city. Her friend asked Li Songqi to keep an eye on him, and she happily agreed.

After they met again, he politely called her "Sis," cooked a delicious spread for her to come home to after work, and picked her up when she worked late into the night.

She thought he had grown up and become more well-behaved.

Then she unexpectedly caught him glaring coldly at her ex-boyfriend, who had driven her home the day before. His voice was icy, as if laced with shards of ice, as he warned him, "Stay away from Songqi."

Li Songqi realized something was wrong and began to gradually distance herself from him, thinking everything would return to normal.

But she never expected him to keep watch outside her door all night, eyes red, voice hoarse as he asked, "Why can't it be me?"

The male lead is a green tea through and through. He seems calm and rational, but inside he's jealous and twisted, often crawling around in the dark.
