Ah... I- I'm glad you enjoyed yourself, then. [Shuffling a bit uncomfortably. He honestly doesn't know what to say]

I can't say for certain but there is a possibility your memories were tampered with. You have been here once before, for several months. The Scientists who bring us here can take us from different time lines and apparently erase our memories of previous stays. Though, sometimes I suppose it doesn't work. I have recalled all three times I've been sent home... some others, are not as fortunate.

If there is anything else I can assist in helping you with or answering, please let me know. It's the least I can do. [For Nii-san.]
