The first chap up to third chap is the past. Chap 4 when MC remembered their past, that's why he is terrified of the white haired guy. The white haired guy is the emperor but in different life. Then chap 7 and up shows the continuation of their past, also shows the root of mc's anger. Hope this helps.
