@comeonnow0 completely agree, as pretty much the author using the offer of the elf like an impacting moment felt incredible flat 'cause it wasn't even hinted, it was 100% sure that she will join.
if his plan was going by himself 'cause his friend really needed it would make sense if he was showing that fear, not talking calmly while waiting for breakfast and waiting another day to go.
the idea of making healer that can't be hit is good, but seeing that so early on the story the bad writing is too noticeable is a bad sign.
Examples of a better story with a similar premise: "the wrong way of using healing magic", the mc is funny to follow, they make jokes at the classic trope of the love interest and the master is a baddass. (also manga has double the amount of chapters and still is a lot more entertaining)
