It's too late now. I should have realised it before.

Eunmi had never known that her childhood bestfriend Kyuhyun had fallen in love with her before he tried to kiss her in the MRT station, a kiss which she had refused.

Now Kyuhyun is the famous evil maknae of Super Junior, and she finally realises how far he is from her, making her feel really sad. To top it all off, she just realised her deep feelings for him; feelings she never thought she had.

After years of staring at him in music videos and dropping her tears one after another, she finally got a chance to change everything. She was determined to tell him her feelings about him, even if he already set his eyes on another girl, so she won't ever imagine the forgotten kiss and regret ever again.
