True Love is a Japanese slice-of-life romance shōjo manga series written and illustrated by Miwako Sugiyama.
Shortly after, their parents officially divorce and the children are separated; Yuzuru moved to America with their father and Ai remained in Japan with their mother.
When she arrives at school, she finds an older boy and she quickly realizes he is Yuzuru, and they share a happy reunion.
A year after reuniting, however, while they are moving into their new apartment, Ai accidentally falls on top of Yuzuru and kisses him.
Shortly after, she visits his high school and meets his best friend, Shuuji, who takes an instant liking to her.
However, during the trip, Ai struggles to hide her despair at being unable to show her feelings for Yuzuru and breaks down.
Yuzuru finds her and tries to comfort her, but when she attempts to subconsciously kiss him, he sends her away and asks Nanoya to be his girlfriend.
Ai begins to avoid Yuzuru, who decides to make up for this by taking her to Shibuya and spending the day with her, and gives her a heart-shaped hair ornament as a birthday gift.
At school, Yuzuru tells her they need to forget what happened but Ai finally breaks down and confesses she loves him.
To cheer her up, Yuzuru starts taking her out on dates after school and breaks up with Nanoya, who refuses to give up on him.
They share a kiss during the fireworks show but when a silhouetted picture of them surfaces, Nanoya realizes Yuzuru and Ai are a couple.
Ai tries to avoid Yuzuru to not draw suspicion and feels uncomfortable when Shuuji starts making romantic advances towards her.
Upon returning home, their mother lashes out at them and forbids them from seeing each other, to the point of keeping Ai confined to the apartment.
Meanwhile, Yuzuru attends a lab research university in America but although he is popular among his peers, he refuses to associate with women, as he too is struggling to cope with his feelings for Ai.
Shuuji runs into Nanoya at a restaurant and he asks her to forgive the siblings and reveals Ai's decision.
In the letter, Mr. Souda wrote he knew about their relationship all along when he saw them holding hands and supported it, and he also revealed that Yuzuru's biological parents were siblings who left Japan and moved to America but were killed in a car accident shortly after Yuzuru's birth and Mr. Souda, who was a close friend, took the child in.
Their mother, who had believed Yuzuru was Mr.Souda’s child by another woman when she met him, forgives her husband for keeping the truth from her.
Yuzuru still decides to continue his studying in America and Ai agrees to have a long-distance relationship because she is only happy they can be together.
Yuzuru purchases couple’s rings for him and Ai, and after vowing to love her forever, they spend the night together.
Ai says she understands Yuzuru's job in America is important to him and is content with a long-distance relationship.
Their mother, who heard about the situation from Nanoya, confronts them, telling them to not give up their dreams for her and Yuzuru thanks her for raising him.
