Send me HC + a word and I’ll write a headcanon about it regarding my character.
Wenhe was born with a congenital heart defect called Ventricular Septal Defect, or VDS for short. (Both lead to two different sites about VDS: click both if you’re curious)
Without all the fancy terminology, basically she had a hole in her heart that prevented oxygenated blood from properly flowing through the chambers. With VDS, the holes can range in size and small ones often close up during childhood, sometimes even undetected.
In Wenhe’s case, though, she was born premature with a hole that was borderline medium, which -considering the state of her birth- could have counted as a large defect for her.
While it didn’t close up during her childhood, it did shrink as the years went on; by the time she was in her final year of middle school, it closed properly.
Because of how long she’d had the hole in her heart, though, Wenhe still portrays some signs of VDS; she tires easily, and sometimes has shortness of breath when she gets overwhelmed more than usual. And, while she may be on the chubby side, her eating is rather poor in terms of quantity (her boyfriend, Miyaji Kiyoshi, is well aware of this and shares a meal with her under the knowledge that she can never finish one). One of the most prominent problem that was a result of having a hole in her heart that was rather large in terms of how it compared to her size as an infant is that Wenhe is considerably shorter than even the average Taiwanese height of about 160cm/5′3, instead being 142cm/4′8.
Even with the hole closed, though, Wenhe’s heart is still rather weak: if she were to get too physically overworked, it could lead to Sudden Cardiac Arrest, or SCA.
As of now -while she’s gotten close to an attack- it’s yet to actually happen. She takes great care in being cautious of how fast her heart beats and is often watched over by her older brother during physical education (he even brings an extra bottle of water for her just in case what a good
But, of course, she’s taking great care in strengthening her heart with dancing (hence the beginning of her Odorite channel on YouTube and NND.
She also is currently learning basketball from the Miyaji brothers (first Kiyoshi, and then Yūya after Kiyoshi graduates), which further aids in helping to strengthen her heart.
Unfortunately, as tiny as she is, she still doesn’t have much stamina and tires out rather easily at times.
