It is a shounen-ai. The MC had just moved to a new house. In his room, he found a hidden way to the attic. The attic seemed to be a room used by the previous owner. He found an old telephone there and dialed the last phone number called. And suddenly someone answered. And that person was his high school crush who had died 10 years ago.
just a random passerby but I looked up "Solo leveling" and the manga has a 9.9 rating!?!!!? Expectations are high and I wanna try it out because that's the highest rating I've seen on this website O^O
