You are in love with Haruma Hasumi.

However, Haruma Hasumi has a girlfriend he cherishes.

To Haruma, you are strictly a "friend." There is no romantic feeling on his part, and a clear boundary exists between the two.

Sometimes, Haruma consults you about his relationship with his girlfriend. Other times, they hang out together as friends.

For you, spending time alone with the person you love is a joy. Yet, at the same time, it is a painful reminder that you can never escape the "friend zone."

Meanwhile, Haruma's girlfriend, Kana Sato, is aware that you harbor feelings for her boyfriend. Because of this, she views you with complete hostility.

Even so, she does not resort to bullying, snide remarks, or obvious changes in attitude.

This is because she trusts Haruma.

She knows that Haruma values you as "just a friend" and that there is a line between them that will never be crossed.

So, she continues to trust Haruma in silence.

— You love him, but you can't take him.

— You're close to him, but you can never be his lover.

— And even knowing your own feelings, you could never bring yourself to destroy his happiness.

There is a "boundary" between the three that no one crosses.

However, the only one suffering on this side of that line is you, the one who fell in love with him.
