कीवर्ड Solitude

Megumi Soutome is a contract employee in the editorial department at a publishing company. She is invited by her colleagues to join them for a drink get-together, but Megumi Soutome declines their offer. She leaves quickly after work. The reason why she is in such a rush, is so she can have a "solo katasu." She enjoys solo activities like eating alone at restaurants, having her own party, and staying at love motels.

The story revolves around the love, friendship and relationships between four characters who meet by chance.
