It isn't his hobby really lol, he messed up the first time so he's forced to continue cross-dressing.
That's it! Thank you @zephyr4...
But he's really cute when he's crossdressing...
You're welcome :)
Yup he's so cute!
as i remember this manga is a shounen.
the hero's hobby is crossdresing and he join to a unique fighting organization.
one of his friend mother is the enemy of this organization who can make a robot.
