How is this? It's marked harem, which I don't mind too much, but what about the fan service? That I don't like at all.

It's only really harem in the sense that the MC is male and the majority of the rest of the cast is hot females. And even better: the hot females are not all madly in love with him! The MC is only interested in one of the ladies and they do eventually get into a monogamous relationship with no dumb communication issues getting in the way. There is one other lady that loves him and it might go somewhere eventually but as of chapter 600 it's still very much one sided.
As for fan service...I wouldn't say it's horrible but also not non-existent. For example, all the characters have only one outfit they always wear and a lot of the womans outfits do tend to be on the revealing side. But each character is put to use so it's not like they only exist as fan service. Overall, I'd say it's easily tolerated if you find the story interesting.

Why is it that one case of indigestion tends to almost kill people in these comics? I had to look it up, and it should only cause serious problems if it's chronic (recurring), and it does not cause fever. I'll have to treat this the same as people getting like deathly ill from the rain or not drying their hair.
(*T^T) I know things are gonna work out, but this is making me so sad. I don't want to see his reaction the the letter she just sent him.
I totally would have talked with the time wizard about what happened and ask for his opinion about what I should do or with the ML. He's also a wizard and might know something to set her at ease. I understand why she hasn't though.
