Toki wo Kakete Koi de Waru

If only he could relive ‘that day’ once more… Natsu, a maths teacher, and Yu, a gym trainer, have been together for ten years and living together for five. Although Natsu realises just how well they’re physically compatible every time they make love, he feels something is missing in their daily life, which is a far cry from the heart-pounding excitement of when they first started dating. Then one day, after hitting his head in the school building and losing consciousness, Natsu finds himself transported back in time to ten years ago! Reunited with Yu, dressed in his school uniform, in the familiar town, Natsu is reminded of the butterflies he felt back then… but what will happen next?
