Except that I think Yeon Ho already knows that. He seemed to have understood that in the most recent chapter anyway. If Jae Ha also understands this then he will arrange to meet Yeon Ho at 1100 in front of the school in the future even though HIS Yeon Ho won't understand why. So even if MC Yeon Ho doesn't meet him there, there is still the possibility that he might have met him in another timeline.
*He might have met him there in THAT OTHER timeline (which might be enough to make THIS Yeon Ho happy).
I didn't see that in the latest chapter, it has always seemed to me like he is trying to change his OWN reality, he even wen't to resolve his personal issues so that when they met it'd be a clean slate. If he's trying to set up a meeting with his alternate self then why is he working on himself for their meeting?

People keep mentioning 2 endings. The events create a timeline split, don't they? Jae-ha listens, but doesn't end up talking to the yeon-ho on the phone, but rather the one ten years in HIS future. This would leave OUR yeon-ho in his misery... -slits wrists-
