It's a commonly accepted thing for the man to be older than the woman in a relationship. That's not the case of the couples in this collection. The boys in these enjoy having a mature girlfriend, while the girls don't mind at all having a man way younger than them. There are no rules for love, just two people enjoying each other's company.

Loving someone from a different age group is an eye-opening and sometimes inspiring experience, especially when romance is involved. Being in love with someone younger or older requires patience and understanding, especially when the one you love is immature. This collection contains heart-pounding romance about the joys of being in a Senpai-Kouhai relationship.
