Even if it is "just" guilt it proves she is not over Chris at all. Once again that means the MC is a rebound not an actual serious love interest for her. She's already hedged about being with him because he's "too young". In addition lying to her parents about who he is doesn't make for a great foundation to build a relationship on. Ada can also add that the MC is "not good enough" just like with Chris since the MC is not only a high school student but also one who had to repeat his senior year.I really don't understand how this narrative has been bled into the story.
Does Ada still have feelings for Chris? Perhaps, I would argue that it is more of a guilt feeling. Why is that? Well, remember that she told Chris that he was not good enough for her. She told MC that she still feels horrible about it. It's the guilt inside her that is making it hard for her to just completely move on from Chris. I mean, think about it, wouldn't any rational person with feelings have a hard time moving on when you know that you hurt someone who you loved? Personally, I would. Plus Ada knows that Chris would do anything for her. Chris even gave his bike for parts so Ada could fix her bike. It all just plays into the guilt she feels for the way she rejected his proposal.
Not to mention that most are underselling how much of an impact MC has on Ada if you choose her path. She's falling for MC. It's clear in the latest update as well since if you choose to tell Ada's boss that you are her boyfriend, she's actually quite happy about it .
Chris also seems to have some issues as well. He had fling with Mikaela (Ada's friend) which means after Ada broke up with him, he slept with Mikaela. Plus, I have a sneaking suspension that he might have tampered with Ada's bike. A wild theory but one that might have some merit.
Overall, I don't understand why people are choosing write off Ada simply because she still "loves" Chris when it is more about guilt.
Now let's get back to bashing the parents, they need to rot.
Also Rose is jealous because Chris is still hung up on Ada. So it's not a one sided thing. Sure they could both be feeling only guilt about how it all ended, but that seems unlikely to me. It is more likely that guilt, love, and regret are all mixed up in how both of them are feeling. Until the two of them sit down and agree to move on OR give it one more chance they both won't be able to give a new partner the chance a serious relationship needs. They are both trying to move on too quickly (just like the MC and his feelings for Naomi).
I feel sorry for Rose because Chris moved on too quickly and she can see that he is still hung up on Ada. And I don't see Ada learning that Chris gave up his motorcycle for her as something that helps them move on. It won't aid the MC in solidifying a relationship with her when she knows the guy she said wasn't good enough sacrificed his treasured possession, gave up his favorite job, and went straight just like she wanted.
