You repaired the front door by upgrading the door frame with a stronger frame and finally a heavier door in hopes that Alice's friend, Marisa, would have a harder time damaging the door.
As you finished putting away your tools, Alice surprised you when she kissed you fiercely on the lips, and you eagerly returned the kiss. Love-making occurred immediately, and in the morning you woke up in Alice's bed naked with Alice, also naked, sleeping soundly next to you. Alice's head was resting on your chest.
A few months later as a crying, though very happy Marisa, announced you and Alice as husband and wife, Reimu, with tears streaming down her face, screamed that your were an idiot and stormed out of the chapel in anger. You didn't care what the damn miko said, because you married the greatest woman in all of Gensokyo if not the entire world.
Before marrying Alice, she explained that she was incapable of having children due to her womb having been damaged by disease when she was a little kid. It didn't matter to you if Alice couldn't bare your children, since all you cared about was being with Alice herself. And Alice was all you wanted.
The decades passed and now you were nearing 70 years old. Alice, being a youkai had remained as youthful looking as the day you met her, and her love for you never wavered, even when you lost both legs to a mysterious accident with a runaway saw blade at the Hakurei Shrine, making you dependent on Alice for mobility.
Despite being healthy, you became bedridden from a mysterious deadly illness shortly after Reimu, now an old, bitter, unmarried hag who still resented you for marrying Alice, visited Alice and you unannounced. Alice retrieved Eirin, the best doctor in Gensokyo, to check you, but even Eirin was puzzled by your sickness and was unable to provide any help.
