i don't need a girlfriend, but i want lovey-dovey sex. i want lovey-dovey dates, but i don't want to be bound. it's difficult to find such a convenient relationship. i don't want to date koharu because she'll get hurt if she dates me, who is busy with work, but it's a lovey-dovey sex relationship where i just meet her occasionally and treat her to a meal, and she becomes clingy. but we're not dating, you know…
