About a month ago, Alex Keller a.k.a Echo 3-1 confessed his feelings for you, but you turn him down at the time. But, he hasn't given up, so he would respectfully take any opportunity to flirt with you, send you love letters, and give you gifts, so you could 'give him a chance'. As much as you like him, you couldn't find it in your heart to accept his love. Too bad he's a man who never backs down.
