The two met in the hospital's courtyard, in front of a pomegranate tree with scarlet flowers in bloom.
Suzuno, who works at the hospital, meets Ryu, a high school student who comes to the hospital for rehabilitation.

If they hadn't met, they would never have hurt each other.
But they probably never would have grown to like each other.

Suzuno is the eldest daughter of a large family with six younger siblings.
It sounds nice to say they have a large family, but this is only the result of her parents repeatedly "making up" after every big fight, and it seems like in this way the couple was stretching out their love in a twisted way that was on the verge of breaking apart.
Proof of this is that at some point, her mother became so exhausted that she left home, leaving her husband and seven children behind.

From then on, Suzuno became a mother figure to her siblings, and even now that they're all married, she continues to live a life of devotion to others.
Even though she was told it was time to think about her own happiness, Suzuno, who had seen her parents longer than any of her siblings,
could never have imagined the happiness that would come from finding a boyfriend, getting married, and having children like the rest of us.

However, Suzuno's outlook on life was greatly changed when she met Ryuu.

Suzuno was put in charge of Ryuu's rehabilitation, and with his bright, smiling, affectionate personality, she felt a sense of comfort as if she was dealing with her younger brother.
Then, one day, she heard Ryuu talk about the emotional distance he felt with his family, and after feeling a painful sense of empathy,
feelings that she should not have begun to harbor began to grow in Suzuno, and as the days of rehabilitation passed, her feelings grew even more.

The fact that they were meeting under the pretext of rehabilitation, the illusion that arises in certain environments, the huge age difference...
She told herself many reasons to put a lid on these feelings. She thought she should put a lid on them.
--I shouldn't fall in love...!

Suzukino's values, which could be called a curse, were rigid and rigid, as she had to do everything for someone and be recognized by others,
but as she dated Ryuu,
she gradually loosened and turned into something warmer.
She realized that the "friendly" behavior she had hated was more fulfilling and happy than ever, and they longed for each other every time they met.

Something was beginning to change within her.
Just as Suzukino herself began to realize this and her happiness with Ryuu began to become a part of her daily life... she was informed of a shocking truth that once again cast a shadow over Suzukino's outlook on life...

The third installment in the "I shouldn't fall in love..." series, which depicts a drama of love and conflict,
is a story of self-liberation as she struggles to break free from the restraints she unconsciously imposed on herself.

When she was able to speak her true opinion, tears flowed and she was so excited she couldn't sleep. This is a story about Suzuno's courage and determination to break away from the idea of ​​meaning in life, where she could only find meaning in giving her all to others and was unable to give her opinions to anyone, and to discover what love is.
