2x2 - Glow of Fireflies

Hotaru resolves to become a changed woman given her new status. She is determined to become thrifty, save, dress appropriately and make herself worthy of her promised future. Who is the woman and child visiting the house and calling her manager and man 'papa' though? Her co-worker misses her period and may be pregnant. Hotaru organizes a children's event and ends up going for a meal of Iberian pig not when she anticipated, where she thought or with whom she planned.
