Koisuru Sefure Himitsu no Deai-kei

After ending a 3-year relationship because her boyfriend found her too responsible, Nanae starts using dating apps to meet men. Some meetings are casual, like dinner, while others lead to more intimate encounters. Despite these experiences, she still feels unfulfilled. During a sudden rainstorm, she grabs the last umbrella at a convenience store along with an attractive young man. Though she resolves to quit the apps, she returns, hoping to find someone as appealing. The next weekend, the person who shows up for a date ends up being that same man.
