THIS SERIES JUST RIPPED MY HEART OUT AT ENDING.... IT BROKE MY HEART FOR WEEKS AFTER WATCHING THE SERIES BUT THEN I REALIZED ITS TITLE JUST MAKES SENSE, "ETERNAL YESTERDAY". THEY ARE LIVING IN THE PRESENT BUT THEN THE OTHER GUY'S LIFE IS ALREADY SOMEWHAT IN THE PAST CUZ HE'S A LIVING CORPSE AND HIS TIME ON EARTH IS ALREADY FINISHED BUT WITH MICHAN'S LIFE AND LOVE ENERGY MADE KOICHI SO ALIVE. BUT IN THE END KOICHI CHOSE TO END THAT NICE AND MEMORABLE TIME WITH MICHAN BECAUSE IF HE STAYED ANY LONGER WOULD MEAN HE WOULD BE FEEDING ON MICHAN'S LIFE ENERGY AND THOSE AROUND HIM. HE IS SO BRAVE AND SELFLESS WHICH BREAKS MY HEART!!!!!!! WHAT IS WRONG WITH THIS JAPANESE BL MAKING MY HEART FLUTTER WITH SERIES SUCH AS "CHERRY MAGIC" THEN BREAKS MY SOUL WITH THE MOVIE "LIFE" THEN AGAIN STAB MY HEART WITH "ETERNAL YESTERDAY"❤❤‍🩹💔😭😭 THERE ARE ONLY FEW JAPANESE BL's THAT ARE SO UNDERRATED BUT SO DAMN GOOD. SOME DOESN'T NEED A KISSING SCENE AND YET THEY CAN TAKE YOU WITH THEIR FEELINGS WITH THEIR ACTING. THIS IS WHY I LOVE JAPANESE BL SERIES..
