Threads of Time (살례탑) is a {{manhwa}} series in the era of Mongol invasions of Korea by Noh Mi-young. It is distributed in English by Tokyopop.

The plot premise is that OrdinaryHighSchoolStudent Moon-Bin Kim has difficulty sleeping due to a recurring nightmare where he's stranded over a thousand years in the past chasing a dark-haired girl into a deep abyss. Before long, the nightmare overwhelms him, and he is unable to tell whether he is Moon-Bin, a Seoul teenager at the end of the second Millennium, or Sa-Kyung Kim, the son of a prominent warrior family in the middle of the first Millennium. People in his present-day life assume roles in his historical life as he struggles to learn exactly who he is and what he's expected to do, straddling a transmigratory portal through time and space. In the present, his school's kendo club battles to stay in the championships but in the past, Moon-Bin finds himself at the threshold of a territorial dispute on the plains of Mongolia...

* ColdBloodedTorture - Sali Tayi's torture of Moon-Bin's mother from the past. Slaughtering all the servants, cutting off her hand, and forcing her to watch as he [[spoiler: rapes her daughter Sa-Lum]].
* DarkAndTroubledPast - Sali Tayi's past.
* DudeShesLikeInAComa - Sali Tayi's [[spoiler: rape of Sa-Lum]].
* ItsPersonal - Moon-Bin wants to kill Sali Tayi partly because he wants to go home, but mostly because [[spoiler: Sali Tayi killed his family in the past that he grew to love]].

* IWantMyBelovedToBeHappy - Atan Hadas eventually [[spoiler: promises to marry Sali Tayi if he doesn't kill Moon-Bin]]. He [[VillainousBreakdown doesn't take it very well]].

* LongingLook
* MurderTheHypotenuse - Sali Tayi comes to this conclusion very quickly when he discovers that Atan Hadas likes Moon-Bin.
