The place where the lost things goes (FE: Robin X readerX Frederick)

(Y/N) POV
The war was finally over, Grima was defeated, Chrom was crowned king of Ylisse, and you gave birth to two adorable children- Morgan and (child name). However, it was a harsh time for you as you had lost your beloved husband, who was Chrom's trusted tactician- Robin. You would always tell stories of Robin to the kids and they would always be so excited and look at you with merry eyes and asked for another. You love your children, and you know Robin loved them as well as you do. You know he was always there, watching his loved ones grow, but perhaps just in another time and place. You'd always feel his warmth whenever you looked at the starry night, it's really lovely.

You finished singing the lullaby (song above) to the children, you made sure the children were asleep before closing the door gently. You smiled, your (son/daughter) Morgan really resembles his/her father, Morgan got his eyes, his personality, and well, everything. You'd always joked about how your son/daughter is Robin's rebirth and all and Morgan would laugh alongside with you.
You missed Robin, he was your everything in the war, he was always there for you and looking out for you. He'd share some of his favourite books with you, you two would share clothings to wear, you sighed, the good old days.
You felt a blanket was wrapped around your shoulders, you looked over your shoulder to see

" Thanks Frederick," you smiled, he nodded and sat next to you, " You shouldn't wear such little clothings, you'll catch a cold," he gestured to your nightgown, you looked at the stars and Frederick did the same. " Still thinking about Robin?" He asked, you nodded, hugging your knees. He rubbed your shoulder and comforted you, " I'm sure he's proud of you (y/n)," you smiled, " I know."

Laughters could be heard from the house as the family of 3 (and Frederick) was enjoying their time playing chess. It was raining, but that couldn't stop them from having fun. As the children were playing a round of chess in the living room, you were making some delicious treats for them with Frederick by your side. " Thank you Frederick, for being there for me during the one of grief," you smiled at him, " It's no trouble, after all, it must be painful to lose a person who were so dear to you," you nodded as you took the pie out of the oven. It's your favourite, you hope the kids would love it as much as you do. You chatted with Frederick while working of the pies, suddenly, you heard knockings on the door. Frederick almost rushed to see whoever was interrupting the sweet moment with his crush, but you stopped him. Dusting the flour off your hands as you grabbed the flour roller and headed to the front door. " Hello, how can I help...you..." the roller fell unconsciously off your hand as the person came to view, a white haired man with a familiar purple clothing greeted you. You stood frozen in the front door, " This...can't be..." you whispered, tears  swelling up.

" So uh, it's been some time huh my dear (Y/N)."
