As I read through more of the LN I think I'm genuinely falling in love with Issei beyond just thinking he's cute/hot. When he's in good spirits it's infectious, when he's hurt physically or mentally my heart aches for him, and when he wins a particularly hard-fought battle I feel proud. He's so charming and likable that even you, the reader, are part of his harem. There's nothing wrong with me and I will not be taking my meds.
