Gyo-ha and Jun-oh were each other's first love at one point, but they ended their relationship due to a lack of sexual compatibility. A decade later, Gyo-ha, who is now an investment professional looking for new opportunities, discovers a dating app called "AM2"—and unexpectedly reconnects with Jun-oh. Seeking more than mere nostalgia, Gyo-ha suggests a casual fling—an idea that Jun-oh is quick to agree to. However, as Jun-oh's emotions deepen, he starts to worry that the past might repeat itself, fearing that his growing affection will only drive Gyo-ha further away. Torn between longing for the past and present desires, can they genuinely maintain a casual relationship, or will their unresolved feelings jeopardize everything? **Original Webtoon:** [Ridibooks](https://ridibooks.com/books/4291007004), [Naver Series](https://series.naver.com/comic/detail.series?productNo=11546414), [Bomtoon](https://www.bomtoon.com/detail/000022), [Lezhin](https://www.lezhin.com/ko/comic/again_some), [MrBlue](https://www.mrblue.com/webtoon/wt_000065751) **Official Translations:** [English](https://www.lezhinus.com/en/comic/fling_thing), [Thai](https://www.lezhinth.com/detail/thwt_3781)
