So I've read this manhua where the mc is so in love with this guy, follows him as much as possible and always give him a 'lunchbox' every morning, waits for him every morning then one time the guy have had enough and told him to stop.. so he reluctantly stopped then tried to distance from the guy then the guy got confused why he was being avoided and he missed the lunch the mc used to give to him and being jelly overnother guy who got close with the mc. The mc i forgot but his hair is between brunette and orange?
