Seo Haein and Ahn Suho have been together since they were babies, their grandmothers are best friends, so they have known each other since they were very young.

Suho has lived with his grandmother since he was five years old, his father worked far outside the city while his mother was gone. And Haein, her parents are often not at home, busy with their work. So she is more often at her grandmother's house or at Suho's house.

Seventeen years have passed.

They grew up as teenagers and became closer, Haein stayed at Suho's grandmother's house for a while after Suho's grandmother insisted on her staying here. She said: "You are a girl, your parents are busy, your grandmother's house is far away, you can't live alone."

Haein can live alone. Absolutely.

But grandma worries made her end up at Ahn Suho's grandmother's house now, but it's okay, it's fun, not like her apartment which was quiet and stuffy.

But slowly, their friendship turned into the seeds of love.

And this is one year after they started dating.
