Boys B4 Flower

Ok, so i finally finished watching boys b4 flower & i watched it from DVD. On DVD it says last episode but it looks like it is not finished. Main thing i wanted to know is what happens at the end? My DVD stops when gu jun pyo losts his memory and does not remember Jan Di. Jan Di is too upset and runs out of his room and at same time Ji Hoo come to console her after that what happens*I DONT NEED FULL STORY AFTER THAT BUT I JUST WANT TO KNOW WHAT THE ENDING PART*
