Watashi, 2-banme no Kanojo de Ii kara

Two people who each have someone they like more than the other have agreed to date as their second choice. They maintain a secret relationship, spending time together and engaging in intimate acts, with the understanding that if either of them has a chance with their true love, the relationship will end. Despite this agreement, both find themselves growing increasingly attached to each other, unable to stop their feelings from deepening. As they continue to draw closer, they become entangled in a complex and emotionally unstable situation, unable to let go even as they acknowledge the risks. The outcome of this uncertain and complicated relationship remains to be seen.
