This is a very 2018 Shoujo Ai oneshot, and I'm loving it.
Yuri/Shoujo Ai have always been a little held back by some old tropes - 'Strawberry Panic' like stories with an Onee-sama, etc. which have been done to death and back. It's good to see more adult life, current world, stories like this, 'Kase-san', and 'New Game!', and from such a talented mangaka like Takemiya Jin, it's just a blessing from the Yuri goddesses.
Looking forward for more Adult Life Yuri/Shoujo Ai, both from Takemiya Jin, and otherwise.
(Also, the art has improved a lot. I'm liking this development)
