Ok so MC(the one who got shot in the head) made a promise to come back for the ML(long hair) who was his lover and a famous opera singer in trouble for offending someone. MC was shot in the head and loses his memories, only remembering the promise to find his "wife," who is a beautiful opera singer. MC is relaying information for the underground network of rebels, gets injured, and is saved by the ML. MC falls in love with ML but won't commit because he can't forget his "wife". ML feels bittersweet, since MC fulfilled his promise but can't remember him. He decides to save the MC and pays a beggar to tell the government a rebel is at his house. ML cuts his hair and pretends to be the rebel, while he poses his unconscious lover as a beggar. ML is chased by the police until he finally jumps into the water at the seaport. In ML's last moments, he sees the peach blossoms in bloom, which is when MC said he would return. When MC wakes up, he hears that the past opera singer and "rebel" had jumped into the sea, and recovers his memories,remembering that his lover was beside him all this time(╯°Д °)╯╧╧
Can anyone summarize this?
