Manta has this BL in English and they've just published ch 64. Only R15 but this story and plot are so beautiful it just gets away with it. The monthly subscription is affordable so please support the artist if you can.
Manta also has No Moral and Stranger, equally wonderful stories. Manta censorship definitely doesn't work for Swapping and The Willow Love Story (R version on Lezhin)😔
Thanks to the uploader who introduced me to this story! You did a great job.
