Ai has always loved her senior coworker, even though she knows he has a girlfriend and should be off-limits. When work runs late and he misses the last train, she invites him home despite knowing it is wrong. After a few drinks, she watches the man she loves sleeping defenselessly beside her and can no longer contain her feelings. Treating it as her final chance, she makes a bold move and whispers, “Please… kiss me.” Their drunken kisses turn into a passionate affair that lasts until morning.
