How can it have a "harem" tag without a "shounen ai" one? Either both or none.
@mitsuki48 I understand that it's a comedy manga, but I can't get how that is relevant. if you say that they are wired to fall in love with him, than it's a shounen ai. it may be one sided or fake. It may have a bad taste and be offensive to actual male couple to make fun of their relationships and I may not like it, but that's a way more than subtext. Let's take Dokunie Cooking, it has little to do with actual cooking or spending pages to explain why food is so good and important, but it has that tag nontheless because it cooks elves with smelly feet to be thrown away soon after because they taste bad: the exact opposite of a cooking manga. It's a comedy on the cooking and not an actual cooking, but it has the tag. I see little to no difference with this one. Or claiming that Evangelion is technically not a mecha. You would be right to do so, but no one cares if it's a fake mecha. in the same way this is more useful if categorized into Shounen ai than not. romance, flirts and love are different things. there can be romance even without love. 2/3 is rather positive.
@thelilyofheaven but they are doing it and because of they are professionals they'll keep on doing that. And I doubt that the hearts will rise if he behaves like that. it was zero until now even if they should be sympathetic with him because they are in the same situation and it doesn't look like they have any intention on going on the friendship route. There'll surely be comedy and thus shounen ai-like events everywhere because it's fun (for the author's target, which is probably a part of those who read shounen ai in the first place, thus the same tag).
Now I shout up, it's not me the one that should choose for the tag. Whoever they are, I hope they have enough elements on both sides to decide. But at least not harem without shounen ai, that's super misleading and doesn't make any sense.
