Any help recognising a handwritten kanji?

Question

I've recently gotten into translating fancomics for a manga, although I'm still a beginner at Japanese. Naturally, I don't really know my kanji and I have to rely on a lot of looking up radical and kanji lists or using OCR (the few times it works). In one of those fancomics, I've encountered a kanji that I've been unable to recognise successfully for a few days now. Here's a pic of the kanji in question.

If I'm not mistaken the top-left radical is 广 and I tried to search based on that (as well as other similar radicals in case I am mistaken). I also tried to look based on the furigana at the left (or at least I think it's furigana) that based on other instances of the artist's handwriting, I took to be に. However, with either of those methods I couldn't find any kanji that seemed to fit the image well enough nor any that seemed to make any sense meaning-wise (though I will admit I could have been missing something as my Japanese is beginner level, after all). For the context of where the kanji appeared, I have this:

告白する相手を間違えてませんか ("Haven't you made a mistake about whom to confess to?" as per my translation) (?)では ないですね The two latter lines are different speech bubbles, but I suspect they might be a single sentence.

If someone can recognise the kanji, I'd grateful for the help, but I'd also appreciate tips on how I might go about this kind of research more efficiently myself. After all, it's very possible I'll come up this problem again in the future and I can't always rely on others.

In any case, thanks in advance for any help.

Answer 1

The character is「嘘」.

_{Assuming that you've identified the furigana correctly, I can't think of a word where「嘘」has a reading「に」. However, I also think that furigana are usually written on the right, not on the left as specified in the question.}

I guess this is a question of character decomposition:

• 「嘘{きょ・こ}」is made from

  • Semantic「口」(mouth, referring to some action by the mouth)

  • Phonetic「虚{きょ・こ}」(referring to the on'yomi), which is made from

    • Phonetic「虍{こ}」 (not「广」). As reinforcement,「虍{こ}」is also the phonetic of 「虎{こ}」.
    • Semantic「丘」(large hill mound), now appearing as「业」inside the character「虚」in Japanese Shinjitai.「虚」originally meant large mound, but this is not relevant to the modern meaning.
