Jansangmani Nameun Geugote

After a terrible fire all but consumes Si-Hu’s home, his life has finally gone back to normal except…he has no memories. An amnesiac, he can’t remember much beyond his own name and the café he works at. Then, one day, his former classmate Ye-Seong Min walks in and helps Si-Hu remember everything that ever mattered: they were in love. From the ashes of his life, comes an old flame.
