First one is this: https://www.mangago.zone/read-manga/shuchu_ni_otoshite_iidesuka/
I also like the second cover.. But.. The second is just a cover the author ma2 did and it is not related with any story :( trashexplorer.tumblr.com/post/737589840611311616/status-complete-oneshot-synopsis-broham
Hey, you sure? cause when I searched the title something vol2 came up.
I searched "liqulle pathos"
Yes. They are just the cover for the volumes for the anthology. But they are not related with any story. The author/artist did a story for the anthology, though. It is called "Suki" to Itte. But not related with the characters in the covers.
