Lifting of the Veil (BL)

When he woke up, he didn\'t know who he was, where he was, or even which year it was. All he knew was that he was somewhat impaired...
There was just sand and he couldn\'t even see a few meters ahead. There were other survivors, and he even found a friend. Was this the apocalypse?
And why is his clingy friend getting clingier as time goes by?

Both MC and ML straight, mutual bending, shou perspective / dual perspective of MC and ML, they will probably be a reversible couple.., love interest falls in love first, there are explicit scenes planned.
Have fun ^^

WARNING: LOTS OF SWEARING, BLOODY, GORE
Cover is of \"Global university entrance exam\" (highly recommended), if I`m not allowed to use this please inform me! MC and ML should generally look like the two on the cover.
