...they are fixing their hair. Brushing? Pony tail? Or... washing it under the shower perhaps? Armpits and torso expoooosed.
...they are doing sports. Working out, playing tennis, basket ball, volleyball or hockey... Or, or or... archery? Hands busy, body exposed, so, grab. that. chance!
...they are doing the dishes, I mean, even this manhwa knows how perfect the chance is, leaving their body exposed 😏
...they are playing an arcade game. Oh no, too ticklish? Keep on trying, don't let that coin go to waste! Evil.
...they are getting (un)dressed. Too easy, but whether they are putting their shirt on or off, or (un)buttoning their pants, there's always room for a brief interruption. with tickles.
...they are baking. Don't you spill a drop of batter, ticklish little lee! 🤭
...they are playing a videogame. Hmm? Too cliche? Cliche = Classic, so just do it. It can be a game console or just a game on their phone, they are gonna be busy, and distracted, so perfect for a surprise tickle.
...they are making a phone call or having a video call. Professional work meeting with colleagues? Even better, just stay out of sight and make them laugh, let's see how creative they are with making up excues for their sudden giggle fit.
...they are singing or playing an instrument. A few pokes and scratches here and there would make it even more melodious!
...they are trying to grab something from the top shelf. That's like literally asking for tickles, isn't it? So give them a hand, or two!
