With the arrival of the Sakura Festival, they made plans to go SAKURA viewing together on this rare holiday. However, an unexpected heavy rain ruined their plan. So, they decided to head home, leaving SHIREN ( Junior Girlfriend) feeling very disappointed... SHIREN carefully takes out the photo they took together earlier and says, "This is the rare photo we took on our date...I must protect it carefully." she said. Seeing SHIREN's reaction, YOONHA (Senior  Boyfriend) thought she was very cute. And with the sight of her being soaked in the rain, he couldn't resist kissing her... How will they make up for this missed opportunity to enjoy the Sakura together...?
