Swamped with work but super excited to read this when I’m free! Thank you for picking it up, I’ve been following the artist for so long so it’s really nice to see a serialised story from them.
It's the iconic BL trope: invite someone found in a pile of trash into your home and fall in love. Try reading the A Man Who Defies the World of BL series, it's amusing seeing all the BL tropes catalogued.
Newer BL generally subvert or avoid them altogether, so they're quite enjoyable. At the same time, I enjoy seeing classic tropes revisited, it's surprisingly refreshing haha.
