Koizumi has expressed his jealousy of Kyon over how much Haruhi clearly loves him in both universes, and on two non-consecutive occasions.

The Disappearance of Haruhi Suzumiya:
>"You keep glancing around. Are you looking for someone in particular? There's no need to worry. We've been taking turns watching over you so there would be someone around when you woke up. Asahina should be coming soon."
>Koizumi gave me a funny look. The look you'd give a friend who completely fell for an April Fools' joke, while laughing at him on the inside. What was that look for?
>"No, I was just feeling a bit jealous. Or envious, if you please."

From The Rampage of Haruhi Suzumiya:
>Koizumi chuckled softly. The hell was that? You're creeping me out.
>"No, I wasn't laughing at you. I was just feeling envious."
>Envious of what?
>"Of the invisible bond of trust between you and Suzumiya."
>"You're going to feign ignorance? No, it's possible that you don't realize how Suzumiya trusts you and you, in turn, trust her."
>How would you know who I trust?
>"Let us assume that we lose the game next week. However, you believe that Suzumiya will not produce closed space as a result. This would be an example of your trust. Likewise, Suzumiya also believes that you will surely lead us to victory. Another example of trust. She was willing to bet brigade members because she genuinely believes that we cannot lose. Neither of you may express it in words, but the two of you are connected by an almost ideal bond of trust."
>I fell into a well of silence. Why didn't I have a response for him? Because Koizumi's speculation more or less hit the nail on the head? I'll let the experts handle the question of whether or not I trust her, but it's true that I don't expect a rampage to break out in Haruhi's mental world.
