Every single one of her "friends" in high school is apparently a part of the cult of Shiraishi. They repeatedly ditch the two of them to be alone together and every time so far she has come back to the group angry but they keep giggling and doing it because Shiraishi asked them to. But the worst part is they are helping to isolate her from Daiki even though she's shown them she was worried about them drifting apart. Her "best friend" literally told Daiki to ignore Wakaba's calls and texts because he was getting in the way of Wakaba's romance while they see her getting depressed about him not responding.

Daiki moves away and rarely comes home to visit at this point. It is known to everyone in their friend group that Daiki and Wakaba have been really close friends since elementary school. Yet, one of the rare times when he shows up to go to a festival with everyone, they send Wakaba and Shiraishi solo without asking Wakaba. She again gets mad at everyone of her "friends" because Daiki is gone by the time she gets back together with the group. Once again none of these people care what she wants and make her walk home with Shiraishi.

Later on, Wakaba gets asked out by Shiraishi and before she can reject him he cuts her off then runs away. Shiraishi then asks Wakaba's "best friend" to nudge Wakaba into accepting and to put even more pressure on Daiki to keep his distance and she agrees to help again. Wakaba tells her "best friend" that she wanted to reject Shiraishi but she tells her that maybe she should just go out with him since she doesn't hate him... She clearly said she didn't want to date him. She wasn't unsure or conflicted about it, she clearly said she didn't want to date him but her "best friend" keeps pressuring her to date this guy because he asked for her help.

Lastly, Wakaba right now is planning to go to Daiki's culture festival to visit him. Shiraishi is already planning to tag along and not let her talk to him as much as possible.

Every "friend" around Wakaba is basically trying to isolate and gaslight her.

Daiki is not wrong for being sooooo reserved about his love considering his past

Daiki's parents aint totally wrong for divorce and remarriage stuff, three of them were forced to do so due to respective families situation, although it ended making Daiki personality like that

Wakaba is not wrong from being "stubborn" about her love and ended up thinking Daiki as lilbro because she was being taught like that since the beginning

Shiraishi is not wrong for loving Wakaba due to her kindness, I mean, everyone has their right to loves someone right?

Chika (Wakaba's close friend) is not wrong for not realizing Wakaba true feeling toward Daiki and decided to support Shiraishi x Wakaba

They are all not wrong by any means, it is just the cruel world forced them to misunderstanding each other

As you guys knew Wakaba (osananajimi) and Shion (New heroine) are both working to loves Daiki in their own ways.

What will Shion going to do after knowing Daiki true personality if by any chance Daiki talk about it?

How about Wakaba? Is she going to have a chance to talk to Daiki? And how she will respond about Shiraishi confession?

How about Shiraishi? As he already confessed to Wakaba and finally going "violent" way by telling Daiki not to be involved to Wakaba although indirectly

How about Chika? After realizing true feeling of Wakaba? Does she will continue to support Wakaba x Daiki? I mean, she even goes as far working together with Shiraishi by telling Daiki to stay away from Wakaba

I can't really blame them as Daiki is already cracked and Wakaba is influenced by how Daiki cope with his situation in childhood, which result in how the story unfold. Ren also not in fault as all fair in war and love, at least until one side says no. Though it was so annoying that Wakaba's closest friend doesn't see Wakaba past her looks.
