The Reincarnator and the Goblin Maiden's Happily Ever After: Using a Past Life to Keep a Joyful Wife

Ginorious Adolni has but one goal after reincarnating into a new world—find and marry someone he can grow old with. After living for close to a century without ever having a single relationship due to his hideous appearance, Ginorious wishes for companionship from the depths of his heart. <br><br> The opportunity presents itself one day when he receives an offer to marry the daughter of the premier duke. It's a shocking proposal for the son of a simple viscount, until he learns that all their attempts to arrange courtships with higher nobles have already failed, and for one simple reason: the daughter's appearance, which has earned her the epithet of the Goblin Maiden. But Ginorious sees his past self in her, and soon learns that she has a genuinely beautiful soul. <br><br> Ginorious resolves to use everything at his disposal, including knowledge from his past life, to make her happy. <br><br> (Source: J-Novel Club)
