IN SEARCH OF PERFECTION...? A company get-together reunites 26-year-old Tsugumi with her high school crush, Itsuki. In the years they've been apart, Itsuki has realized his dream of becoming an architect—but along the way, he's also suffered a spinal cord injury that's left him in a wheelchair. Seeing Itsuki again rekindles Tsugumi's feelings for him. It also forces her to confront her own hidden prejudices. Itsuki's disability seems like an intimidating obstacle at first, but soon, Tsugumi discovers that her world feels imperfect without him.

Tsugumi Kawana has started dating her first crush, Itsuki Ayukawa, who's in a wheelchair. However, the deeper and deeper their love gets, the harsher the realities they face become. And at the appearance of Itsuki's caregiver who has feelings for him, Nagasawa, and Tsugumi's classmate who has feelings for her, Koreda, everything begins to fall apart as emotions are stirred…

After her breakup with Itsuki, Tsumugi leaves Tokyo for her old home in Matsumoto...and after one stormy night, she finds herself in a relationship with Koreda! Tsugumi thought she was over Itsuki, but she meets Kaede, who uses a wheelchair, and Keigo, her boyfriend who wants to build her a house that meets her need...and, shockingly, Itsuki refuses to design it for him! The news plunges Tsugumi's heart into turmoil... Meanwhile, big changes are in store for Nagasawa and Itsuki's relationship.

Keigo asked Itsuki to design a barrier-free house so he can be together with Kaede, who uses a wheelchair … but Itsuki said no. Now, Tsugumi’s headed for Tokyo to try to convince Itsuki to change his mind. Tsugumi doesn’t know how to feel about seeing him again, but she does her best to let Itsuki know how Kaede feels. Moved by Tsugumi’s sincerity, Itsuki agrees to take the job. Before they part, he asks her a surprising question: “Is he looking out for you?” How will she answer? Feelings collide and emotions clash in Volume 6!

UNLIKELY ALLIES Things seem to be going more smoothly for Tsugumi and Itsuki—their complicated past aside, collaborating on a new project together seems to allow them an ease that eluded them in romance. On the morning of the ribbon cutting, however, there is a big earthquake in Tokyo, and Tsugumi can't reach Itsuki. In her panic, she turns to the only person she can think of to help her make sure Itsuki is okay...

Now happily married, Tsugumi and Itsuki start their life as newlyweds. Their relationship and careers are going smoothly, and they cherish the everyday moments shared together. They couldn’t ask for more, but when they start thinking about the future, they inevitably wonder how they feel about starting a family. But having a child is proving to be a challenge for the couple, especially for Tsugumi...
