Thanks a lot. This is the tankōbon (collected volume) of the manga. The epilogue added at the end and the revisions to the last two chapters are excellent. However, compared to the physical edition, the digital version is missing the physical edition’s inner cover (which features the heroine specially wearing lingerie).
Starting from page 12 of the first tankōbon volume, it differs from the serialized version. Correspondingly, for the last two chapters of the serialization, the author modified the texture of the heroine’s lingerie and the positions of the mosaics in the tankōbon.
