Window to window gave me more second hand embarrassment tbh
https://www.mangago.me/read-manga/ganbare_nakamura_kun/ (the sequel is probably even more embarrassing)
https://www.mangago.me/read-manga/i_ship_my_rival_x_me/ (mc gave me a LOT of anxiety omg)
https://www.mangago.me/read-manga/golden_sparkle/ (this one is just because of how innocent the mc is)
https://www.mangago.me/read-manga/online_game_nakama_to_sashi_off_shitara_shokuba_no_onijoushi_ga_kita/ (...the catalyst to this plot is so damn embarrassing pls)
https://www.mangago.me/read-manga/toritan/ (this one's only a little bit embarrassing bc the mc literally CHIRPS to talk to birds)
