Hm.....if she lost her memories....shouldn't she have like....been able to check the date?? Seeing how many years have already passed, shouldn't she be surprised by the year? Even the thing with her phone, after many years, I'm sure it changed at least once X'DD? RIght now, she seems really crazy X'D
And lol, why is her husband so calm with all her antics? Is he reasoning her strange behaviour with her grandma's death?
