Only for a "short" while...

All was going well for Natsuki and the rest of the club except for Sayori who has been sick lately. Yuri seems to start to warm up to Natsuki, that's until they deicide to ride a ferris wheel when Monika gets lost at a carnival.
Something blocks Natsuki's memories and she doesn't remember Yuri.
What will she do now?
Will Yuri ever tell Natsuki how she really feels?
