I have a theory. Maybe the ML Prince is also a regressor and he loves the MC originally, then for some reason he died so he wished to turn back time but lost his memory in the process, but the feeling is still there (lol). I remembered when MC was poisoned during tea party there's a memory where ML is crying beside him begging not to leave him again so that's my basis. And the reason why MC is regressing again and again is because the ending is not right, he should be with ML instead
