Youth is ignorant and love is just beginning. Where will the relationship of the four people go?
I'm watching from behind, I just want you to be happy;
I will guard you and follow your footsteps, as long as I can see your smiling face.
I love you without asking for anything in return, I love you without asking for the result;
Between long-distance protection and close companionship, who can win this young love?
Two sisters who grew up together, two boys who became brothers because of a fate,
Who is whose destiny?
The simple and confusing road of love allows them to experience the test of friendship and the torment of brotherhood.
Where will they drift to in the end?
Which one is the real her, her in reality or her on the Internet?
