yes I agree. Since they live some distance away. Traveling back and forth would be a hassle and she would need the funds and time to do so. Which right now she probably doesn't have either.
I feel like Shiharu is getting closer to the time where she has to plan for college and get ready to move out of the orphanage so she'll be really busy soon.
Also, sadly, although she loves the twins she is nothing more than an outsider (harshly said). She can't just go visit them whenever she wants, everything must be plan out. If its far away distance she needs to plan it on days she doesn't work or have school. She also need to ask permission if she wish to stay over. And most importantly, knowing Shiharu, she wouldn't want to be bother for those around her and wouldn't act selfishly.
Now it would be a different story if she gets together with Seiji (which we all know that its going to happen) because she'll be their aunt-in-law. But since Seiji wants to wait 10 years.... it going to be a long (but lovely) road.
It makes me cry even harder now the kids have realized it :") it's so cute and adorebol. I hope this manga turns to an anime since I really love this also there's enough chapters to make that happend :)
