In the deal, he was told not to reveal anything about himself, I'm guessing something bad would happen if the father found out that his youngest son found the fraud. Why else would he want to erase his existence about the past ? We're still not seeing everything you know, we don't know what the full picture is. All we see is the MC's POV. Who knows? The ML might be acting he doesn't know anything and might be finding a good time to tell him everything.
Just because a person with amnesia lost memories, doesn't mean their whole body will forget everything. Since the MC can't change their face, of course they'll look similar from years ago. You can still distinguish someone's face from years ago, unless they got surgery or you have face blindness.
(Pls don't take this the wrong way, I'm not trying to be rude. Js trying to explain Σ(っ°Д °;)っ. Haven't read the novel, so Idk if this has any. spoilers.)
Lol, your comment wasn't rude at all, so no worries. And that's what I'm talking about he can't change his face, his whole body won't forget everything. And it's those moments that aren't reflected enough within the story. It's very very very small. And I understand that we are currently looking through the MC POV but even those moments of what happened are very small too. We already know what they spent time with each other in the past, what we don't know is what happened after that. Like with the grandfather, the son and the ML accident. For us being 40+ chapters we should be seeing more of that aspect of the story. We are still on them having day dates, and have moments in the house, or meeting ppl who are close to the ML's family.
And don't get me wrong those moments are sweet, but we honestly didn't need a chapter about when the dog got lost, or meeting that girl when she was a kid. Them showing his mom yes or them going out to drink yes because it could have revealed or hinted at that he knows the MC is a guy. But my point is that the story is spending to long in the honeymoon faze and not showing any progress into the after honeymoon faze. If that makes scene.
I really love this story...I just hate that he's not telling him he was the fiance. They story isn't really giving a lot into the ML remembering his past. That aspect of the story is moving to slowly, we are 40+ chapters and we barley had any hints reflecting he's remembering anything. And if he does know, I hate that we are waiting to tell the MC "like hey I remember everything." I just feel like we are getting no where. Just a lot of foreshadowing but none of it moving the present story along or why he ask the MC to come stay with him.
