Ripples in the River Vol 1

A sweet Boys’ Love manga about falling in love over and over again, even after a decade of being together! From the creator of 5 Seconds Before a Witch Falls in Love—also available from Seven Seas. Tamba and Utagawa have been together for over ten years, but Uta still can’t believe he’s landed such a stud, and Tamba still gets blindsided when his young-at-heart boyfriend switches into adult mode. It’s a nonstop whirlpool of love that sends both their hearts skipping!
