To Heart 2 AD

Scars of Memories — Takaaki has recently lost his memory, and the girls do everything possible to help fill in the gaps with more or less pleasant memories while keeping him from remembering what happened.

Within this, Tamaki seems to have a specific memory that she holds dear involving a particular letter.

Happy New Year — Takaaki and his group of female friends visit the shrine and spend the night until the first sunrise of the new year together.

They get fortune cookies whose (mostly negative) predictions all turn out to come true in a strange way; there is only one predicting a positive outcome: Yuma whose luck poem tells her she will "fall in love with someone close to her whom she did not see with much interest before"... could that be Taka-kun, her "eternal enemy"?
