It's unironically my favorite spinoff/iteration of this work. Probably because we've watched all these characters suffer too much, and this is our chance to see them just leisurely enjoy life.
No temptation has overtaken you except what is common to mankind. And God is faithful; he will not let you be tempted beyond what you can bear. But when you are tempted, he will also provide a way out so that you can endure it.
given that this was originally a visual novel. depends on the route! though... one of the options is probably cooking breakfast during this scene. and the sister is one he never actually considers in any route (the creator intended to make a sister route but then decided the protag wouldn't go for it part way through. so she (white hair) has a one sided interest. meanwhile. he is just like my adopted father had a wife and kid I never met? too bad mom is dead. I would love to have a little sister though (neverminded that she is older and more magically powerful than him.)
