With hope swelling in my chest, I started working for Tofugu.
I kept it to myself that I got mosquito bites on my breasts, making them very itchy.
The lyrics to the Tofugu theme song, which Koichi sings every morning, with his chest puffed out, cause a swell of emotions in my own chest.
The kanji and the word are exactly the same. That means they share meanings as well.
This vocab word uses the same reading as the one you learned with the kanji. At least I won't have to bring up the image of you mooning (むね) people with your breasts or whatnot. Oh dang, I just went and did it.
