On Tuesday, Kodansha's K MANGA service declared that they have made First Love, Worst Love! ( Yori-kun to Yori o Modosu Wake ni wa! ) by Sumio Hataya available in English.

The company describes the story:
"Please refrain from starting any new romantic relationships at this time." After moving to Tokyo for college, Hatsuho was excited for her upcoming college life until she discovered that her neighbor was none other than her former high school boyfriend with whom she had an awkward breakup. Despite his condescending attitude, his good looks made it difficult for her to hate him. Unfortunately, Hatsuho is now facing the beginning of her troubles with her problematic ex-boyfriend.
On March 24th, Hataya started the series in Kodansha's Dessert magazine. On August 12th, they released the first book volume of the series.
